Mr Johnson has tested positive for coronavirus, Downing Street says. His symptoms are mild and he will continue to lead the government response to the virus while he self-isolates, a spokesman says.
“Over the last 24 hours I have developed mild symptoms and tested positive for coronavirus. I am now self-isolating, but I will continue to lead the government’s response via video-conference as we fight this virus. Together we will beat this,” Johnson said on Twitter.
