Prime Minister Boris Johnson is "in good spirits" after spending the night in intensive care being treated for coronavirus, No 10 has said.
A spokesman said Mr Johnson, 55, was stable overnight and is being given oxygen and is not on a ventilator.
It comes as Cabinet Office minister Michael Gove became the latest politician to self-isolate after a family member showed symptoms.
Mr Gove said he did not have symptoms and will continue working at home.
Mr Johnson was admitted to St Thomas' Hospital in central London with "persistent symptoms" of Covid-19 on Sunday and was moved to intensive care on Monday at 19:00 BST after his symptoms worsened.
