Boris Johnson is able to walk again after he was moved back from intensive care to a hospital ward, Downing Street says.
A statement from Number 10 said: "The prime minister has been able to do short walks, between periods of rest, as part of the care he is receiving to aid his recovery.
"He has spoken to his doctors and thanks the whole clinical team for the incredible care he has received.
"His thoughts are with those affected by this terrible disease."
Mr Johnson was rushed to hospital on Sunday night after his COVID-19 symptoms worsened.
