Prime Minister Boris Johnson has tested positive for coronavirus (Covid-19).

A Downing Street spokeswoman said: “After experiencing mild symptoms yesterday, the Prime Minister was tested for coronavirus on the personal advice of England’s Chief Medical Officer, Professor Chris Whitty.

“The test was carried out in No 10 by NHS staff and the result of the test was positive.

“In keeping with the guidance, the Prime Minister is self-isolating in Downing Street.

“He is continuing to lead the government’s response to coronavirus.”

In a video posted on social media, Mr Johnson said: “I have developed mild symptoms of the coronavirus, that’s a temperature and a continuous cough. And, on the advice of the chief medical officer, I have taken a test that has come out positive, so I’m working from home, I’m self-isolating. That’s entirely the right thing to do, but be in no doubt that I can continue, thanks to the wizardry of modern technology, to continue to communicate with all my team to lead the national fight back against coronavirus.”
