Boris Johnson moved to Intensive Care Unit due to coronavirus

A spokesperson told the BBC that since his Sunday evening admittance into St Thomas' Hospital, the Prime Minister's condition had worsened.

"On the advice of his medical team, he has been moved to the Intensive Care Unit at the hospital."

The statement continues: "The PM has asked Foreign Secretary Dominic Raab, who is the First Secretary of State, to deputise for him where necessary. The PM is receiving excellent care, and thanks all NHS staff for their hard work and dedication."

The prime minister announced that he had contracted the virus on March 27 in a video published on Twitter.

Johnson was reportedly in "good spirits" and was continuing his work as leader of the government only hours before being admitted to ICU, a spokesperson said.

Johnson, 55, thanked "the brilliant [National Health Service] staff taking care of me and others in this difficult time."

Johnson was brought into ICU ten days after he tested positive.
