In Downing Street’s latest daily televised press conference he thanked the country for its “huge efforts” to comply with the government’s advice.
Mr Johnson said “we can turn the tide within the next 12 weeks”, adding: “I’m absolutely confident we can send the virus packing in this country.”
He has been joined once again by the UK’s chief medical adviser, Prof Chris Whitty, and chief scientific adviser, Sir Patrick Vallance.
Boris Johnson says coronavirus is “proceeding in a way that does not seem yet to be responding to our intervention”.
But he says with the combination of measures the government has put forward, the UK can “get on top of it in the next 12 weeks”.
The PM adds: “I cannot stand here and tell you by the end of June we will be on a downward slope.
“We don’t know where we are, how long this thing will go on for, but what I can say is this is going to be finite, we will turn the tide and I can see how we can do this in the next 12 weeks.”
Chief scientific officer Professor Patrick Vallance adds we are “at the beginning” of where the measures put in place “should be starting to have an impact on the rate of growth”.
