Prime Minister Boris Johnson will speak with President Donald Trump on Tuesday and meet Queen Elizabeth later this week, his spokesman said.
The Downing Street spokesman added that the British leader is still not "formally doing government work."
Johnson is recovering at his country residence after he was hospitalized with Covid-19. His foreign minister, Dominic Raab, is standing in for him while he recovers.
"Yesterday he sent a message of condolence to (Canadian Prime Minister) Justin Trudeau after the very sad loss of life in the shooting in Canada," the spokesman told reporters, referring to the shooting rampage in Nova Scotia. "Later today ... he will be speaking to President Trump."
The spokesman said the meeting with the queen later this week will be the first in three weeks.
