Freddie ljungberg takes temporary charge. Good evening. Two people have died in what the metropolitan police are describing as a terrorist incident on London Bridge. The attacker was later shot dead. Several members of the public managed to wrestle him to ground, and their bravery has been widely praised. Police say the attack started here, in fishmongers hall, at the northern end of the bridge. The alarm was raised just before 2pm this afternoon. The attacker then appears to have moved onto the bridge, where he was tackled and disarmed amid chaotic scenes. Police then arrive at 2 03pm, five minutes after the first emergency call. Armed officers then fire two shots, killing the suspect, fearing he was wearing an explosive vest. The Prime Minister, who is chairing a cobra meeting in downing street right now, said earlier that any accomplices to the attack will be hunted down and brought to justice. The mayor of london, sadiq khan, praised what he called the breath taking heroism shown by members of the public who tackled the suspect before police arrived. Tonight, large parts of Central London remain cordoned off, and police say extra patrols will be on duty across the capital. Our correspondent Daniel Sandford is at the scene tonight. Yes, clive, once again a major bridge in Central London is closed following a suspected terrorist attack, which killed two people. Once again it involved knives and a fa ke once again it involved knives and a fake bomb and once again police had to kill the suspect. The attack started at fishmongers hall, at what is thought to have been a criminal justice event and what is thought to have been a criminaljustice event and the main suspect is thought to have been a former prisoner attending that event. My report of the day contains some distressing details. Distressing details and pictures. It was a crisp winter afternoon in the city of london just before 2pm. The panic starts. Passengers filming from a bus see armed officers pointing their weapons. There is a struggle on London Bridge and two of the officers go forward. Beside the melee is a man standing with a knife which he is taken from the suspect. He runs with it as armed officers shout, get back. They pull away a man who is wrestling with the suspect and then opened fire. Gunshots. 0h suspect and then opened fire. Gunshots. Oh my god there were two loud pops. When he was lying on the floor, after the pops, he then sort of pulled hisjacket back and you could see underneath that there was some sort of vest, whether a stab vest or an explosive vest, and at that point the Police Officer really backed away. Of course, i was really scared at this point because we were about as close as the Police Officers in our bus, so yeah, that was scary. There was more firing and the suspect, who the police say was wearing a hoax bomb, died at the scene. I can confirm at this time we believe a device that was strapped to the body of the suspect was a hoax explosive device. The London Ambulance service declared a major incident. At least five people who had been stabbed were taken to hospital, but two of them died. My heart goes out to their loved ones and to the three further injured victims who i understand are being treated in hospital, and of course to everybody who has been affected by todays terrible and mindless events. The attack started in fishmongers hall. People attending a criminaljustice event there said at least one woman had been stabbed. Shocked witnesses from the hall, some of them with blood on their clothes, were ushered away and driven off in a bus commandeered by police. Then the area was flooded by armed officers and other specialist teams, as all the surrounding buildings were evacuated. Its 3 20pm. Normally at this time on a friday the city is buzzing, the bars open, people starting to make their way home. But this evening its sealed off with armed officers and officers with dogs patrolling every street. This evening, with a good section of the city still closed off the leaders of the two main parties were defiant. I think the message that we send to them and anyone associated with this type of attack is one that will be familiar and that is that this country will never be cowed or divided or intimidated by this sort of attack, and our values, our british values, will prevail. We have to remember that we live in a Democratic Society and those that would seek to silence us will not succeed. Our democracy must be alive and vibrant. Tonight a fullblown terrorism investigation is under way. Three and a half weeks ago the threat level was lowered from severe to substantial, but today, the city was reliving the horrors of the London Bridge attack two and a half yea rs London Bridge attack two and a half years ago. Daniel sandford, bbc news at London Bridge. In a moment, well hear from our deputy Political Editor john pienaar in downing street. But first, lets speak to Sarah Campbell, whos at new Scotland Yard for us tonight. Watmore are saying . The metropolitan police have given two statements here today, giving this clear timeline of events. So the commissioner, cressida dick, described how the event started at fishmongers hall with the police receiving the first call at 1 58pm this afternoon and she said just five minutes later city of London Police had confronted the suspect. In terms of what is happening here this evening, Counter Terrorism detectives, she said, would be working around the clock to identify the victims and to help their families, whilst at the same time working at full tilt, she said, to understand what happened and crucially whether anyone else was involved. In practical terms, crucially whether anyone else was involved. In practicalterms, in london, this does mean that those cordons around London Bridge will remain in place for some time. London of course very busy at the moment with shoppers and with tourists and as a reassurance the commissioner said that people would expect to see more police on the streets, both armed and unarmed, and anyone with any information is asked to call the anti terror hotline. Straight to you, john, in downing street. Any word yet from that cobra meeting being chaired by Boris Johnson . We wait for word after that meeting. Its taking place behind me here at number ten, the Prime Minister in the chair, the siddique khan, the mayor of london is in the meeting too. Sadiq khan. The minister is being fully briefed on the Police Operation and latest intelligence and his job since the operation has been running on well planned and practised lines with no need for political interference, hes had a big job of articulating the view of the country, so he spanked the emergency services, hes praised members of the public who stepped in at some risk to themselves he thanked the emergency services. He articulated the message of defiance which has been picked up by leaders of all the parties. Borisjohnson been picked up by leaders of all the parties. Boris johnson has been picked up by leaders of all the parties. Borisjohnson has stepped back from campaigning, the labour party has suspended campaigning in london this evening but when campaigning picks up as normal you can naturally expect that security and confronting the threat of terrorism will rise higher up the Election Agenda in coming days. 0k, john, thank you for that, john pienaar in downing street and Sarah Campbell at new Scotland Yard. Our security correspondent Gordon Corera is here. What is the latest on the investigation into all this . Initially that looked similar to the attack on London Bridge two years ago in which innocent people appear to be targeting at random at the bridge and Borough Market but our picture has evolved somewhat as to what might have happened today. The incident did start in fishmongers hall, where there was a criminal just this Research Meeting taking place. The person believed to be responsible is, the bbc understands, thought to be a former prisoner, and ive been told there is a connection with that event in terms of what has happened. Now, there was no intelligence, no advance warning, that anything like this could have happened, although there will be questions about it. The threat level against the uk was actually brought down a level from severe to substantial at the start of the month, reflecting that theyd seen less potential attack planning and activity recently. The one thing they will think though is the actual response to the attack did happen very quickly, thanks to the police, thanks to members of the public. Now it turns to the investigation, understanding the details of the man, whoi understanding the details of the man, who i understand has been identified, understanding what motivated him specifically, whether he was targeting specific people, and crucially whether there were any other connections, and whether there is any residual threat out there. If there is then we may see that threat level go up but at the moment it hasnt gone up. Gordon corera, our security correspondent, thank you. In cardiff, during tonights bbc Election Debate, all the participants expressed their horror at the events on London Bridge and paid tribute to the victims and the emergency services. The debate itself saw heated exchanges over brexit, with conservative claims they could get brexit done being described as a lie, and labours position branded as a cop out. Our Political EditorLaura Kuenssberg is in cardiff for us tonight. At the technicians pack up in cardiff, inevitably and quite rightly probably this debate that began with a more sombre tone to reflect the events of what has happened in london, less of the hurly burly, less of the political pantomime that dominated much of this Election Campaign so far. There we re this Election Campaign so far. There were serious clashes though and serious conversations over the issues that divide and unite us. Seven politicians, seven parties, all here tonight fighting for their corner. A clash of political shades, a rainbow of seven party colours. Taking the stage together in an election with a debate taking a more serious turn. Acknowledging and asked how they would tackle the kinds of events that took place 150 miles away. What do the Panel Members propose to do to tackle Security Issues in the uk in future . The first duty of every government is to keep us safe and, of course, a conservative government will continue to do that, investing in our police, giving them the resources and the powers they need. Weve seen over 20,000 Police Officers cut from Front Line Services so, it is right to recognise that would have a direct impact and, of course, weve got to invest more in Community Neighbourhood policing. We have to make sure that we support our security services, that we keep access to the best intelligence, which is one of many reasons i think leaving the European Union is a mistake. We have set out plans to increase Police Numbers by 20,000. I think it is also important that we look at what the police do in that community policing. Suggestions, too, though, the police take a different approach in preventing terrorism. I think we need to look again at the prevent programme because i think we need to make sure it is enjoying as much confidence in every Single Community in our country as it can and im not sure right now it is. We must keep investing in more police and more technology. But however many police we have, and we need as many of those police as possible on the streets. Then a clash over the two big parties big differences on spending. I think you were referred to recently in the media talking about the figure of 1. 2 trillion spend, which is a fabricated lie the conservative party have been perpetrating over the last few weeks. You look at people like the ifs, respected think tanks, they describe the labour plans as simply not credible. Theyve said they are wholly unprecedented. They shout over each other. Can i just finish . Theyve also said, theyve said clearly it would be ordinary working families that pay the price in higher taxes. We need to look for parties that will set out where they will get the money from and we are saying very honestly we think the nhs needs more money and we will raise income tax by a penny in the pound in order to do so. Then the core question, how to conclude brexit or stop it altogether. I was a remain voter but feel we are so far along the brexit journey now that it has to go ahead. How do those of you here this evening feel about talk of a second referendum . We are so not far along in this brexitjourney. The idea brexit is going to be done, we are like in episode one of a ten season box set and if you dont like what youve seen up until now, you dont have to watch the rest. It is going to take us years to negotiate a new trade agreement. It took seven years with canada. The idea youll get it done through this is simply a fantasy. Nobody but nobody thinks a trade deal can be negotiated and agreed by the end of next year. We do yeah, but we dont trust you, sorry. I dont trust you because you dont trust brexit you dont trust 17. 4 Million People borisjohnson, of course, insists it is possible. You said he couldnt get the brexit deal, it would be impossible but he did. He did get a great new deal and he got it in three months. It isnt a great deal, it is a dreadful deal. No wonder people dont have faith in politicians when the leader of the labour party that wants to be Prime Minister wont even tell us where he stands on the central question that is going to cast its shadow on a generation. It is right thatjeremy acts as an honest broker in this because he needs to get a good deal with the European Union and i think stating how he would vote in a final public vote would undermine that. As ever, this elections about the health service, too. The nhs is failing. What are you going to do to stop this and make sure it isnt sold to the highest bidder . The nhs is not for sale, never has been and never will be. Documents were released. Let me finish, it is only polite to let me finish. Documents were released this week that showed very clearly the government had been involved in numerous discussions with us trade officials. It is a desperate conspiracy theory. We are absolutely crystal clear, the nhs wont be on the table. The price the nhs pays. The nhs pays for drugs will not be on the table. When borisjohnson says the nhs is not on the table in a future trade deal, i simply do not trust him and i do not believe him. Last, how would they greet the controversial visitor, donald trump . If you had 30 seconds with him, what would you say . Happy thanksgiving. Im a good catholic so i wont say probably what i would say to him. Lets get a quick trade deal done. And here is our nhs, is what he would say its pathetic just lying to the british people continually, its pathetic i think you have form on that. Applause. Resign and take boris with you. At the end, there were some friends on stage but theyd be wise to hug their political enemies closer still. Laura kuenssberg, bbc news, cardiff. There were passionate arguments tonight but no grand revelations you think might upset what really has been stable tram lines running through this campaign. That finale on Donald Trumps imminent visit, though, a reminder there are plenty of events, clive, left ago in what is now less than a final fortnight when the public in the end on thursday, in ten days time, will have made its decision. 0k, have made its decision. Ok, laura, thank you. Laura kuenssberg live in cardiff. The Energy Supplier npower is to cut to up to 11,500 jobs in the uk, as part of restructuring plans to make it more profitable.
