As it happened: UK PM Boris Johnson warns of second wave of infections - BBC News
Boris Johnson believes it is 'inevitable' that a second wave would reach the UK at some stage.
Boris Johnson, asked if the government had eased lockdown too quickly, suggested discipline in adhering to social distancing restrictions had slipped.

"If you look at what's happened over the last few months, I think the British people have done a amazing job," he said.

"They got that peak under control, they brought it right down, they brought the number of infections right down by discipline and everybody adjusting our behaviours and the way we go about our lives - hands, face, space.

"And I think probably, truth to tell, what's happened here and what alas has happened in so many other countries is that people find it difficult to keep this up."

He said it was "very difficult to maintain that kind of discipline for a long time".

And if the "rule of six" in England or the tighter restrictions in parts of the UK do not work in curbing the spread of the virus, "then of course we are going to have to take further measures", the prime minister said.

"But be in no doubt that we will want to be explaining what we are doing, taking people with us as we go and what I don't want to do is go into a second national lockdown of the kind we had in March, April - I don't want to do that again."
