Boris Johnson has told US President Donald Trump he is "on the road to recovery" as he recovers from coronavirus at his Chequers country retreat.
In a sign the PM was making a gradual return to work, Downing Street said they discussed the need for an international response to the pandemic and a post-Brexit trade deal.
The White House said Mr Johnson "shared that he is feeling better" during the call. The two leaders also discussed the need for co-operation to "reopen global economies", the White House said.
Mr Johnson is expected to have a telephone audience with the Queen later this week for the first time in three weeks, during which he spent time in intensive care with Covid-19.
