UK Labour Leader Keir Starmer is self-isolating after one of his children tested positive for coronavirus this afternoon, as the country records 44,104 new Covid cases and 73 more deaths.
"I know it's my responsibility to follow the rules - my family and I are now self-isolating," Mr Starmer said in a statement.
This is the fourth time Mr Starmer had to isolate since the pandemic began.
Just a couple of hours before the news broke, Mr Starmer was in the chamber of the House of Commons, quizzing Prime Minister Boris Johnson over his self-isolation after being 'pinged' by the NHS Covid tracker app.
Mr Johnson answered questions via videolink from the prime minister's country residence at Chequers, where he is isolating.
Mr Johnson, Minister for Finance Rishi Sunak and Minister for Health Sajid Javid are all isolating afterMr Javid tested positive for Covid.
Alerts, or "pings," sent out by the official app telling anyone identified as a contact of someone with the disease to self-isolate for 10 days have caused huge disruption in schools, businesses and the healthcare system.
The crisis, which comes just as the Government lifted nearly all restrictions in England to help drive an economic recovery, has been dubbed the "Pingdemic."
Today's figures bring the total number of recorded Covid cases in the UK to 5,563,006, while to total number of recorded deaths now stands at 128,896.
