THE Prime Minister's condition has worsened and he has been moved to intensive care.

Prime Minister Boris Johnson has been moved to intensive care after his coronavirus symptoms worsened, Downing Street has confirmed.

The PM was admitted to St Thomas' hospital in Westminster on Sunday following advice from doctors.

He has had symptoms for 10 days, but having been in hospital for further tests, he has been admitted to intensive care.

Delyn MP Rob Roberts wished the PM a speedy recovery.

He said on Twitter: "All the best to our friend @BorisJohnson for a full and speedy recovery.

"You and @carriesymonds are in our thoughts sir."

Foreign Secretary Dominic Raab will "deputise where necessary", a Number 10 spokesman told the PA news agency.

The spokesman 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 PM is receiving excellent care, and thanks all NHS staff for their hard work and dedication."

It came just a few hours after Mr Raab told a press briefing that the PM remained in charge of the Government despite remaining under observation.

The Conservative Party leader is understood to be conscious and has been moved to the ICU at about 7pm as a precaution should he require ventilation to aid his recovery.

At a press conference less than two hours before the decision was made, Mr Raab told a press briefing that the PM remained in charge of the Government despite remaining under observation.
