Exterior of hospital where UK PM is being treated

British Prime Minister Boris Johnson was moved to the intensive care unit of a London hospital after his coronavirus symptoms worsened on Monday, just a day after he was admitted for what were said to be routine tests.

Johnson was admitted to St. Thomas’ Hospital late Sunday, 10 days after he was diagnosed with COVID-19.

“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,” his office said in a statement.

Downing St, said Johnson was conscious and does not require ventilation at the moment, but was in the intensive care unit in case he needed it later.

It said Johnson has asked Foreign Secretary Dominic Raab to deputize for him.

Hours earlier, Johnson tweeted that he was in good spirits after spending a night in hospital.
