July 19, 2021 British Prime Minister Boris Johnson. Reuters LONDON - British Prime Minister Boris Johnson and Finance Minister Rishi Sunak will both self-isolate in line with national guidance, dropping heavily criticised plans to take part in a pilot scheme that would have allowed them to continue working. Both had been exposed to a person with Covid-19. The U-turn comes a day after Health Minister Sajid Javid said he had tested positive, and at a time when the government's coronavirus response is under intense scrutiny. Almost all remaining restrictions in England will be lifted today despite a surge in infections as ministers put their faith in the vaccine programme.
