LONDON — U.K. Prime Minister Boris Johnson agreed to work with Donald Trump to fight the coronavirus pandemic in a telephone call on Tuesday afternoon.

Downing Street said in a statement following the call that the leaders had agreed on the importance of "a coordinated international response to coronavirus," including through the G7, which is currently chaired by the U.S.

They also committed to signing a free-trade agreement between the two countries "as soon as possible.”

Johnson, who is recovering after being admitted to intensive care with COVID-19, is not formally back at work yet. His Foreign Secretary Dominic Raab is still deputizing, the prime minister's spokesman said earlier on Tuesday.

White House Deputy Press Secretary Judd Deere later tweeted that the "prime minister shared that he is feeling better and on the road to recovery."

Raab will on Wednesday stand-in for Johnson at weekly questions session in the House of Commons, which is now operating virtually.

The U.K. prime minister, who is recovering at his grace and favor property Chequers, will also speak to the queen by phone this week, Downing Street said.
