British Prime Minister Boris Johnson, who was in hospital due to persistent coronavirus symptoms, has been taken into intensive care after his condition worsened, Downing Street said on Monday.

UK foreign secretary Dominic Raab has taken charge as Johnson, 55, was moved to the ICU at St Thomas’ Hospital in London.

A spokesperson for No 10 Downing Street said: “Over the course of this 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.

“The PM has asked Foreign Secretary Dominic Raab, who is the First Secretary of State, to deputise for him where necessary,” the spokesperson said.

“The PM is receiving excellent care, and thanks all NHS (National Health Service) staff for their hard work and dedication.”
