UK Prime Minister Boris Johnson is self-isolating after an MP he had a meeting with later tested positive for COVID-19.

The prime minister said he had been notified by NHS Test and Trace that he has to self-isolate as he has been in contact with someone who has tested positive.

Mr Johnson tweeted: “I have no symptoms, but am following the rules and will be working from No 10 as I continue to lead the government’s pandemic response.”

Mr Johnson had a meeting lasting about 35 minutes with some MPs in Number 10 on Thursday morning, including Lee Anderson.

Mr Anderson then developed symptoms for COVID-19 and tested positive.
