To be the whistle blower whose claims have prompted impeachment proceedings against President Trump. Tens of thousands of people working for the police in england and wales have not been properly vetted, a watchdog report has found. The world athletics championships get under way in doha later with britains athletes set to endure scorching temperatures as they bid for gold medal glory. And in angola, prince harry walks through a partially cleared minefield 22 years after his mother diana did the same. Good morning and welcome to the bbc news at 9 00am. One of the Prime Ministers most Senior Advisers has said he is not surprised that some voters are angry with mps over brexit. Dominic cummings said the only way the issue of abuse would be solved is if mps respected the result of the eu referendum, and said its not surprising if people are angry with the way parliament has responded to the referendum result. The parliamentary tensions have more than 100 archbishops and bishops to warn against further entrenching our divisions calling for respect on all sides, amid growing acrimony over the debate on britains withdrawal from the eu. Borisjohnson has defended the language he used in wednesdays commons debate, after he described one mps safety concerns as humbug. But the prime minster insists he deplores any threats to anybody, particularly female mps. 0ur Political CorrespondentJonathan Blake is at westminster. First of all, jonathan, good morning to you. To those comments made by Dominic Cummings. What has been the reaction to what he has said . This comes reaction to what he has said . This co m es after reaction to what he has said . This comes after Dominic Cummings, the Prime Ministers most Senior Adviser in no 10 downing st, and of course, the former strategist behind the successful vote leave ca m pa ig n, the former strategist behind the successful vote leave campaign, was confronted in parliament by one of those mps who is angry at the kind of language the Prime Minister has been using and the tactics deployed by no 10. He was confronted in parliament by karl turner, a labour mp, accused of being a disgrace. That mp said he had had Death Threats over night and confronted mr cummings about that. The response was, in that case, to say that mps should get brexit done. Speaking last night Dominic Cummings went further at a book launch in london saying that whilst threats of violence should be taken seriously, he went on to say that people shouldnt be surprised that people are angry about the fact that brexit hasnt been delivered yet. I will read you a bit of what he had to say. If you are a bunch of politicians and say we swear we will respect the result of a democratic vote and then after you lose you say we dont want to respect the vote, what do you expect to happen . 0n the pressure the government is facing, he dismissed that really, saying this is a walk in the park compared to the referendum. We are enjoying this, he said, we are going to leave and we are going to win. While they have been calls for calm and a lowering of the level of debate here after an extraordinarily weak at westminster, the Prime Minister himself saying that the temperature needed to come down, Dominic Cummings striking something of a slightly more defiant tone. Good morning. Why are you blaming everybody . Who is blaming who . Why are you blaming him . It doesnt look like a walk in the park, does it, mr cummings . A walk in the park . Who said it would be a walk in the park . You said it last night at a book launch. No. Jonathan, as things stand, the law says if borisjohnson hasnt got a deal by the middle of october, then he has to request that the eu would give the uk and extension. But there have been concerns that he might try to find a way around that law, and sirjohn major has been talking about this, hasnt he . Yes, the former conservative Prime Minister john major putting forward his theory as to how the circle can be squared, if you like, with the Prime Minister on one hand saying the government will abide by the law but on the other saying he has no intention of asking for an extension to brexit, which he is now required by law to do if a deal isnt reached by law to do if a deal isnt reached by the 19th of october. Sirjohn major speaking yesterday saying that he sees some possible way forward for the government by using a mechanism of the privy council to find an act of parliament which would allow them to suspend the act which requires the Prime Minister to ask for an extension until after the sist ask for an extension until after the 31st of october. A lot of technicalities involved, obscure bits of parliamentary and government procedure, which sirjohn major talked about in his speech last night, with a warning to the Prime Minister as well, but it would be entirely inappropriate and in flag ra nt entirely inappropriate and in flagrant defiance of parliament, utterly disrespectful to the supreme court. As to whether that is what the government is going to do or not, they are keeping us guessing. The chairman of the conservative party james the chairman of the conservative party ja mes cleverly the chairman of the conservative Party James Cleverly gave his response on question time last night. What im not going to do is im not going to talk through how the government intends to discharge its business, knowing full well there are a whole load of people who will try to distort every procedure we have in british politics to try and prevent that. So, the debate continues. There is come later on, a meeting between brexit secretary Steve Barclay and michel barnier, the eus chief negotiator in brussels. No Huge Movement expected then, but perhaps some substance for people to talk about which may detract from the ongoing debate here at westminster. Jonathan, thank you very much for that. Jonathan blake. With so much discussion about the language being used in politics right now. We can speak to alex from demos. The latest group of people to weigh in on this, the church of england bishops and archbishops, calling for people to moderate their language. How much has the divisive language. How much has the divisive language to do with social media platforms and the rise of social media . I think social media has made the abuse, the harassment and intimidation of mps more accessible, more visible, easier to carry out. But i think alongside that we have seen a rise of this kind of politics, the politics that is toxic, divisive and that thrives on social media platforms. But i think for the rise of that politics we need to look further than that. And look to wear, alex . We have seen it is notjust how your bodyis we have seen it is notjust how your body is an online space but how you can exploit it and itjust happens to be the fact that at this divisive, toxic politics thrives on platforms like social media and beyond. So what changes can be made to these platforms, do you think, or can changes be made . That will make a difference . At the same time one wa nts to a difference . At the same time one wants to encourage debate. People buy law are free to express their opinions. Thats right. The debate often focuses on how we police this content better. Of course that is one way in which social media platforms can do more. We need to be more ambitious than that. It is quite clear the social media platforms and internet platforms we use for our politics and our democracy are simply not fit for purpose. They are designed for this function. I would encourage people to build new spaces, online Spaces Designed to have healthy, Democratic Politics in mind. Though space is being heavily policed, presumably, to allow robust debate through but not abusive debate through . Policing is certainly one aspect of this and it is clear. And very tricky, presumably, alex. How many people would you need to do that sort of thing . Of course, it requires a lot of human oversight and Technological Development to identify different kinds of abuse through machine learning, a process or an algorithm. It isa learning, a process or an algorithm. It is a challenge and it is one the social Media Companies are tackling everyday but more needs to be done on that. Alex, good to hear your thoughts this morning. Alex krasodomski jones, from demos. Senior us democrats say a whistleblowers letter which has been made public proves that donald trump tried to cover up details of a phone call he had with the president of ukraine. In the call, mr trump pushed for the Ukrainian Government to help smearjoe biden, his leading rival in next years us president ial election. Mr trump denies exerting improper pressure, but the call has triggered an impeachment inquiry against him. David willis reports now on that and the evidence given to congress, yesterday, from americas acting director of national intelligence. David willis has more. A beleaguered President Trump returned to the white house last night. Even by the breathless standards of his administration, the last few days have been particularly tumultuous. A whistleblowers report maintains not only that mr trump misused the office of president for personal gain, but that white house officials, alarmed by his request for dirt on democratic rival joe biden, then sought to bury the evidence. In the days following the phone call, i learned from multiple us officials that senior white house officials had intervened to lockdown all records of the phone call, the whistle blower rights, especially the official word for word transcript of the call. This underscored to me that the white house officials understood the gravity of what had transpired in the call. President trump seen here with mr zelensky earlier in the week has lashed out publicly and privately. At a closed door event in new york, he suggested that white house staff who spoke about the telephone conversation should be seen as traitors. Democrats in the house of representatives launched a formal impeachment inquiry earlier this week. 0n capitol hill, the battle lines are being drawn along party lines. This phone call is a nothing burger in terms of a quid pro quo. The president of the United States did not remotely suggest to the ukraine, if you dont do my political bidding against the bidens im going to cut your money off. Donald trump is going to choke on this supposed nothing burger. He will go down with this supposed nothing burger in his throat, because what it shows is repeated, concerted and premeditated criminal conduct. Last night, President Trump renewed the attack on his political rivals. Ijust watched a little bit of this on television. Its a disgrace to our country. Its another witch hunt, here we go again. Its adam schiff and his crew making up stories and sitting there like pious. Whatever you want to call them. Itsjust a, really, a disgrace. The president s personal lawyer Rudy Giuliani is emerging as a central figure in the effort to dig the dirt onjoe biden. Last night, an infuriated mr giuliani lashed out at his critics. Now, why are they doing this . What they are really trying to do is to intimidate me and to discredit me because im doing such an effective job of showing what phonies they are. The president is not without his supporters, however. Sheriffs from across the us converged on the white house, looking to raise his spirits at the end of a brutal week. Seven days ago, most people in america had yet to hear of mr trumps fateful conversation with the president of the ukraine. David willis, bbc news, los angeles. Prince harry is in angola to help with land clearance of mines. He is walking in the footsteps of his mother by walking through a cleared land mine field. It gave added impetus to a un treaty banning landmines. Prince harry spoke while visiting the site praising the clearing efforts to help the Community Find peace. Landmines are an scar of war and by clearing their landmines we can help this Community Find peace, and with comes opportunity. Additionally, we can protect the diverse and unique wildlife that relies on the beautiful cuito river that i slept beside last night, and that river and those wildlife are your natural assets, and if looked after will bring unlimited opportunities within a conservation led economy. 0ur royal correspondent Nicholas Witchell sent us this report from angola. It is 17 years since the civil war in angola ended, yet there are still more than 1,000 minefields scattered across the country. Prince harry, following the lead set by his mother who came to angola in 1997 shortly before her death and highlighted the whole issue of minefields, he arrived here a short time ago, he had a briefing on this particular minefield close to the border with namibia. He has now gone into the minefield, he has seen the painstaking work which is done by the mine clearers, inching their way through the minefield metre by metre, checking for mines. When they find one it is removed. It is a huge problem in this country which they are now tackling with the help of the halo trust, that is a British Organisation leading the de mining effort in angola. Later, harry will go on the city of huambo, where his mother Princess Diana came in 1997. Those unforgettable images of her walking through a minefield which led eventually to the passing of the ottawa convention, which finally criminalised the use of antipersonnel landmines.

It comes as more than of the church of englands bishops and archbishops issue a rebuke to politicians for using what they call unacceptable language in the fierce debate over brexit. In the us, a cia officer is reported to be the whistle blower whose claims have prompted impeachment proceedings against President Trump. And in sport.

Captain alun wynjones will become wales most capped player of the coach Warren Gatland named an unchanged side to face australia in tokyo on sunday. I will be back with more than those stories after 9 30am. It is claimed there are still significant gaps in the governments no deal planning in relation to the nhs in care homes. The National Audit office praised the department of health and social care for the enormous amount of work that had been done but said there were still risks involved if the uk left the eu without a deal. Andy moore sent this report. From rubber gloves and syringes to medicines and blood product, the entire health and social care system in the uk relies heavily on medicines and equipment imported from the eu. Much of this comes via the channel ports which could see huge disruption in the event of a no deal brexit. Even though mps have passed a law to stop a no deal brexit, the department of health and social care have been working on ways to minimise the risk, should it happen. But todays report from the National Audit office says some serious questions remain unanswered. Even with six weeks supply or some stockpiling going on, if there is not a simple way of getting medicines into the country or if theres a hold up at any point, the stockpiles will go down quickly and they need to be replenished so theres an awful lot to play for, an awful lot we dont know because it will depend on what happens in other countries as well. A no deal brexit could cause serious disruption to medical supplies, not least because, of the 12,300 medicines licensed for use in the uk, around 7,000 come from or via eu countries. The governments own worst Case Scenario means a no deal brexit means cross channel goods could be cut by up to 60 . Means cross channel goods could be cut by up to 60 . A statement from the department of health and social care reassured patients that everything was being done to make sure they could access medicines after brexit, whatever the circumstances, and the departments preparations were unprecedented. But the nao report makes clear that with just weeks to go before a possible brexit, much work remains to be done. Andy moore, bbc news. Lets get more on this now from rebecca sheeran, the executive leader of the National Audit office. Thank you forjoining us. There is some really interesting detail in this report about what the government has done so far in terms of this sector. For example, you say in terms of high volume supplies like gloves and syringes, as of 20th september the government stockpile was at 88 . So doing pretty well on that area. What else has the government done so far . The government done so far . The government has done an enormous amount to prepare and manage risk to disruption. It has taken a multilayered approach, which we think is a very sensible approach, of looking at stockpiling, as you have mentioned, looking at its own stockpiles for the nhs, but also looking to encourage pharmaceutical companies to make their own stockpiles for a six week period. In addition to stockpiling, it is also looking at doing what it can to make sure that goods continue to flow ac
