UK headed into full lockdown next month if Boris Johnson doesn't fix 'disastrous' test and trace …

Britain could be headed into another full lockdown if Boris Johnson doesn’t to sort out the “disastrous” test and trace programme, a former government adviser has said.

Sir David King told the Sunday Mirror the the UK is “nowhere near” the safe reopening of schools, adding: “We need a proper test and trace system by September. Otherwise full school opening will put us right back.”

Sir David, 80, the former chief scientific advisor to Tony Blair who now heads the Independent Scientific Advisory Group for Emergencies shadowing the PM’s scientific team, called on Mr Johnson to “get it right”.

He said: “The Government has a month to deal with the level of infectivity as it stands now. Reopening schools should be a priority, but we believe we are nowhere near the point where it can be done safely.”

The R rate of infection number is expected to rise by about 0.5 when all schools open.

Sir David urged the PM to let councils run test and trace as he hit out at the current system, run by private firm Serco.

“Tracing here is one phone call and you are asked to isolate. There is no follow-up as to whether people do,” he said, adding: “The Government made a disastrous mistake giving contact tracing to a firm with no healthcare expertise.”

It comes as , writing in the Mail on Sunday, said it is the “national priority” to get all pupils back into classrooms in September after months without in-person education.

“This pandemic isn’t over, and the last thing any of us can afford to do is become complacent,” he wrote.

“But now that we know enough to reopen schools to all pupils safely, we have a moral duty to do so.”
