Prime Minister Boris Johnson has been admitted to a London hospital for tests, Downing Street have said.
He has had persistent symptoms, including a temperature, and has been sent to hospital to have a series of routine tests.
A Downing Street spokeswoman said, “The prime minister thanks NHS staff for all of their incredible hard work and urges the public to continue to follow the government’s advice to stay at home, protect the NHS and save lives.”
The prime minister remains in charge of the government, but the foreign secretary chaired a coronavirus meeting this morning.
Last month, the prime minister’s spokesman said if Mr Johnson was unwell and unable to work, Mr Raab, as the first secretary of state, would stand in.
