Prime Minister Boris Johnson has been told to self-isolate as a contact of someone with a confirmed case of Covid-19.
The PM must now enter a period of isolation but is well and is not showing any symptoms.
A Number 10 spokesman said on Sunday night: “The Prime Minister has today been notified by NHS Test and Trace that he is required to self-isolate as a contact of someone who has tested positive for Covid-19.
“The Prime Minister will follow the rules and is self-isolating. He will carry on working from Downing Street, including on leading the Government’s response to the coronavirus pandemic.
“The PM is well and does not have any symptoms of Covid-19.”
Ashfield MP Lee Anderson, who had a breakfast meeting with the Prime Minister in Downing Street on Thursday, said in a Facebook post: “Isolating. On Friday I lost my sense of taste at the same time my wife had a bad headache. I had no cough, no fever and felt well.
“We both had a test on Saturday and the result came in Sunday morning. y wife and I both tested positive.
“I feel absolutely fine and my biggest concern is my wife who is in the shielded group. But we are both feeling good.”
Earlier this year the PM had coronavirus and was badly ill. He was treated in St Thomas’ Hospital in London, a short distance from Downing Street.
He was admitted to hospital on Sunday, April 5, having tested positive for Covid-19 on March 27. The Conservative Party leader was admitted to intensive care the following day as he required oxygen support.

Hours before he was taken to intensive care Mr Johnson tweeted to say he was “in good spirits and keeping in touch with my team, as we work together to fight this virus and keep everyone safe”.
The PM left the intensive care unit on Thursday, April 9, but remained in hospital for further observation. He was said to have been in good spirits and reportedly waved to hospital staff as he returned to the ward.
He tested positive for coronavirus on March 27 and was taken for hospital tests at that point. His symptoms included a high temperature and a cough and he spent more than a week in self-isolation before being admitted to hospital.
Mr Johnson left hospital on April 12 but said it “could have gone either way” as he paid tribute to healthcare workers for saving his life.
