Boris Johnson has tested positive for coronavirus.

The prime minister has mild symptoms and will self-isolate in Downing Street, but will continue to take charge of the government’s handling of the crisis.

He posted a video on Friday morning on Twitter saying he has a temperature and a persistent cough. “I am working from home, I’m self isolating, and that’s entirely the right thing to do,” he said. “But be in no doubt that I can continue… to communicate with all my top team and lead the national fightback against coronavirus.”
