Boris Johnson has abandoned his plan to avoid quarantine after being contacted by NHS Test and Trace following a violent political backlash.

Prime Minister and Chancellor Rishi Sunak originally planned to have daily tests rather than self-isolation following meetings last week with Health Secretary Sajid Javid who tested positive for Covid-19.

But in a dramatic turnaround, Downing Street said the two ministers would self-isolate rather than participate in a daily contact test pilot.

“The Prime Minister has been contacted by NHS Test and Trace to say he is someone’s contact with Covid,” a spokesperson said.

“He was at Checkers when contacted by Test and Trace and will stay there to self-isolate. He will not participate in the test pilot.

“He will continue to conduct meetings with ministers remotely. The Chancellor has also been contacted and will also self-isolate if necessary and will not participate in the pilot. “
