Prime Minister Boris Johnson has tested positive for coronavirus, he has confirmed. 

He is experiencing mild symptoms, Number 10 says. 

"He was tested for coronavirus on the personal advice of England's chief medical officer, Professor Chris Whitty," a statement said.

He will still be in charge of the government's handling of the crisis, the statement added.

The test was carried out at Number 10 by NHS staff.

In a tweet, Mr Johnson said: "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."
