Biden arrived at Stansted airport on Sunday night, according to an AFP journalist.
On Monday, he will meet Charles III at Windsor Castle for the first time since the Briton’s coronation, at which Joe Biden was represented by his wife Jill Biden.
The two heads of state should mainly address environmental issues, according to the White House. The US President will then meet Prime Minister Rishi Sunak at 10 Downing Street.
But the highlight of Joe Biden’s tour will be the NATO summit on Tuesday and Wednesday in the Lithuanian capital Vilnius, where Western allies will discuss supporting Ukraine against the Russian invasion.
The democrat hopes to use the opportunity to convince Turkey to accept Sweden’s NATO candidacy.
In a phone call with Turkish President Recep Tayyip Erdogan on Sunday, Biden “conveyed his desire to welcome Sweden into NATO as soon as possible,” the White House said.
Both “expressed their commitment to continue supporting Ukraine,” the statement added.
Erdogan’s office noted in turn that the Turkish president would meet Biden during the NATO summit in Vilnius.
The talks will focus on “Ukraine’s position in NATO, Sweden’s accession to NATO, and the delivery of F-16 fighter jets,” which Turkey hopes to get from the United States, the Turkish presidency said.
