Dominic Raab, the foreign secretary, will deputise for Boris Johnson if he is incapacitated by the coronavirus, according to the prime minister’s official spokesperson.

Johnson was admitted to hospital on Sunday for tests after experiencing persistent symptoms of coronavirus ten days after testing positive for the virus.

If the virus prevents the prime minister from carrying out his duties, Raab will step in.
