UK Prime Minister Boris Johnson, who has been in hospital for a day with coronavirus, has been taken to intensive care.
A No 10 statement read: “The prime minister has been under the care of doctors at St Thomas’ Hospital, in London, after being admitted with persistent symptoms of coronavirus.
“Over the course of [Monday] afternoon, the condition of the Prime Minister has worsened and, on the advice of his medical team, he has been moved to the intensive care unit at the hospital.”
A Downing Street spokesman said he was receiving “excellent care”.
The 55 year old UK Prime Minister has asked Foreign Secretary Dominic Raab to deputise “where necessary”, the spokesman added.
The Queen has been kept informed about Mr Johnson’s health by No 10, according to Buckingham Palace.
The UK Prime Minister is the first world leader to be diagnosed with COVID-19. He tweets regularly, his last post a day ago when he was admitted as a precautionary measure according to Downing Street.
