any connection. he was asked by the police still believe that sarah might be alive and he would simply say that police were helping and doing their utmost to try and find her, just coming up to a week now when she was last seen. there's no clear evidence that it has led to a reduction in coronavirus infection. that's the damming assessment of the nhs test and trace system by a group of mps. the commons public accounts committee has urged the government to justify what it calls the staggering investment of taxpayers' money into the system. nhs test and trace in england has received £37 billion in funding since it was set up last spring. the report says the purpose of the test and trace system was to help prevent further lockdowns — the uk has since had lockdown 2 and lockdown three. and, there has been an over—reliance on the use of consultants — with some paid over £6,500 a day. the transport secretary grant shapps said the report on test and trace �*defies logic�* as it is helping to bring down the number of infections. here�*s our health correspondent, anna collinson. identifying the infected, locating their contacts and isolating — a well—functioning test and trace programme is seen as crucial in the fight against the coronavirus. but a damning report is questioning whether england�*s system is effective enough to justify its cost — £37 billion over two years. it�*s an eye—watering sum of money that�*s been spent. and for that, we need to see better results and a better, clearer connection between testing and stemming the spread of the virus. and so far the data on that is not very strong. the budget for test and trace was £22 billion when it was set up last may. a few months later, the person in charge, dido harding, requested a further 15 billion — claiming the main driver would be to avoid a second national lockdown. but two lockdowns followed, and a group of cross—party mps say the service must demonstrate its worth. the public accounts committee has particularly questioned test and trace�*s continued reliance on consultants, with some paid more than £6,600 a day. and it�*s claimed the system was unable to cope when schools returned in september, and there was a surge in demand. but dido harding disagrees. nhs test and trace is an absolutely essential component in the fight against covid. we�*re hitting all of the targets that sage set us and, you know, as we speak today, we�*re providing an extra layer of security and confidence. despite the vaccine roll—out, new variants mean we can expect test and trace to continue to play a key role in our lives. but many will be watching closely to ensure taxpayers�* money isn�*t wasted. anna collinson, bbc news. 0ur chief political correspondent, adam fleming is at westminster.

what is interesting for me is that they quote a report prepared by the government itself and published last month but i only saw today, looking at the effectiveness of this and it says their best guess is it reduces the number of people that get coronavirus on average from each infected person and the government thinks that test and trace overall reduces that our number from between 18 to 33% which is quite a big range. they say within that, the contact tracing that might only beat responsible for two to 5% of that. it really is not clearjust how well the programme works. that was not the programme works. that was not the message from the transport secretary who has been doing interviews today and he says it is crucial and it does work. i think that finding defies logic but ask— i

the president of the european council published a i european council published a newsletter last night where he says the uk had a ban on exporting vaccines to other countries. the uk government says that is absolutely not true and it said this in a letterfrom the foreign not true and it said this in a letter from the foreign secretary to him last night. this morning, an eu diplomat in london has been summoned to the foreign office to speak to a top civil servant at their to get a diplomatic dressing down and in terms of the eu has said, they have been gradually downgrading what charles meant. they started off by saying there was a ban and then last night they chilled journalists it was more like something that was tantamount to a defective ban and now this morning they say it was more of a tactic to rattle the cage of the uk media to get them talking about whether astrazeneca is sending enough doses of the vaccine to the eu. for me and last week i was picking up people suggesting that may be in brussels that it is time for a reset between the key —— uk and eu relations so they get more friendly but that doesn�*t seem to be happening at all. we can speak now to the liberal democrat mp, sarah 0lney — she sits on the public account committee which has published this damming report on nhs test and trace. he was contacted by a test and trace call centre back in august — more than a week after he should have finished his self—isolation we know about this £37 billion figure set aside for the government to pay for its test and trace system over two years, tell people watching what else money is being spent on? from our report and inquiry, the bulk of the money is going on testing infrastructure to the test kits themselves, the testing sites, the staff. a lot of infrastructure has been built up over the last year to manage the scale of testing and there is no doubt that we have scaled up testing very dramatically. there are far more tests being carried out now than in the early days of the pandemic last spring so thatis days of the pandemic last spring so that is where the bulk of the money is going. what we were very concerned about as a committee and our remit is to look at whether or not taxpayers money is being spent wisely and what we were concerned about was some of the spending that was going on creating capacity so for example, in the call centres there was a lot of surplus resource in call centres. sometimes only 1% call centre capacity was being used in a day and the maximum was no more than six to 5% so a lot of surplus capacity was being paid for in the call centres and we were also concerned about the number of consultants still being paid on a very high day rates. we would have liked to have seen by this stage a much more embedded process working closely with local authorities where we don�*t need, there was obviously a need early on to buy in outside expertise to get things up and running but we would have expected to see that reduced by now and we feel there are still too many consultants on day rates. 2,500, is that correct? _ consultants on day rates. 2,500, is that correct? are _ consultants on day rates. 2,500, is that

resources to be planned to cope with those surges but what we are saying is, was there too much surge capacity planned for and was it in the right place at the right time? we know there was a surge for testing in september when the schools and back but the operation was not well—planned to deal with that. did we have the right surge capacity at the right time in the right places? i don�*t think there is much, someone needs to review and have a look and say, 1% capacity of your resources being used, as a 20 being deployed in the right way? this is from the chair of test and trace, after building a testing system from scratch, we have now carried out over 83 million tests, more than any herbal uk country and yesterday conducted 1.5 million tests. test and trace has successfully reached 98.6 of the contacts. do you accept f test and trace hadn�*t worked so successfully then they would have been a wider spread of coronavirus in this country? it spread of coronavirus in this

programme in terms of actually stopping the transmission. the original 22 billion that was committed to test entries in this current financial year was justified on the basis that it would prevent further lock downs. since that has happened we have had two further lock downs so that is why we are questioning why there isn�*t more evidence to show what effect test and trace on its own has had in reducing transmission of this virus. what is your experience of test and trace, what was your main concern? my trace, what was your main concern? my experience comes from last august when my— my
