Prime Minister Boris Johnson is “still very much in charge of the government” despite spending the night in hospital with coronavirus, Housing Secretary Robert Jenrick has said.
The PM was taken to a London hospital on Sunday evening with “persistent symptoms” – including a temperature – for a series of routine tests.
It is said to be a “precautionary step” taken on the advice of his doctor.
Mr Johnson, 55, tested positive for coronavirus 10 days ago.
Foreign Secretary Dominic Raab will chair Monday morning’s coronavirus meeting in his place, Mr Jenrick said.
Last month, the prime minister’s spokesman said if Mr Johnson was unwell and unable to work, Mr Raab, as the first secretary of state, would stand in.
Mr Jenrick told BBC Breakfast: “We hope that as a result of these tests [the prime minister] will be able to come back to Downing Street as soon as possible.
“He’s been working extremely hard leading the government and being constantly updated. That’s going to continue.”
“I’m sure this is very frustrating for him, for somebody like Boris who wants to be hands [on] running the government from the front, but nonetheless he’s still very much in charge of the government,” he added.
US President Donald Trump is among those who has sent his wishes to Mr Johnson.
“All Americans are praying for him. He’s a great friend of mine, a great gentleman and a great leader,” Mr Trump said, adding that he was sure the prime minister would be fine because he is “a strong person”.
And Labour leader Keir Starmer said he hoped the prime minister had a “speedy recovery”.
Health Minister Nadine Dorries, who herself tested positive for coronavirus last month, said many of those with the virus would be “felled” by fatigue and a high temperature and use isolation to sleep and recover.
“Boris has risked his health and worked every day on our behalf to lead the battle against this vile virus,” she said in a tweet.
