Boris Johnson has abandoned plans to avoid quarantine after being contacted by NHS Test and Trace following a furious political backlash. The Prime Minister and Chancellor Rishi Sunak had originally planned to take daily tests rather than self-isolate following meetings last week with Health Secretary Sajid Javid who has tested positive for Covid-19. But in a dramatic turnaround Downing Street said the two ministers would be self-isolating rather than taking part in a daily contact testing pilot.
