Prime Minister Boris Johnson has spent the night in intensive care at a central London hospital after his coronavirus symptoms worsened.

Mr Johnson, 55, is “in very good hands”, said Foreign Secretary Dominic Raab, who has been asked to deputise for the PM.

Mr Raab arrived at No 10 on Tuesday and chaired the government’s daily Covid-19 meeting.

World leaders have sent messages to Mr Johnson wishing him well.

Mr Johnson was admitted to St Thomas’ Hospital with “persistent symptoms” on Sunday and moved to intensive care on Monday at 19:00 BST.

He was moved as a precaution so he could be close to a ventilator – which takes over the body’s breathing process – BBC political correspondent Chris Mason said.

Cabinet Office minister Michael Gove told BBC Radio 4’s Today programme on Tuesday: “The prime minister’s not on a ventilator. He has received oxygen support.”

If there is any change in his condition “No 10 will ensure the country is updated”, Mr Gove added.

Mr Gove is the latest politician to announce he is self-isolating at home, after a family member showed symptoms.

As the first secretary of state, Mr Raab is the minister designated to stand in for Mr Johnson if he is unwell and unable to work.

Mr Raab said earlier there was an “incredibly strong team spirit” behind the prime minister and that he and his colleagues were making sure they implemented plans Mr Johnson had instructed them to deliver “as soon as possible”.
