London AFP July 10 : President Joe Biden arrived in Britain Sunday where he will meet King Charles III and Prime Minister Rishi Sunak before continuing to Vilnius for a NATO summit, then a final stop in new NATO member Finland.

Air Force One touched down at Stansted Airport north of London late in the evening, an AFP journalist reported.

On Monday, he meets the British monarch at Windsor Castle, one of the royal residences, for the first time since Charles III’s coronation.

The US president did not attend the ceremony, sending First Lady Jill Biden instead.

Their talks are expected to focus on environmental issues, the White House said.

Biden will also be meeting with Sunak at 10 Downing Street.

The main part of Biden’s Europe trip will be the NATO summit in the Lithuanian capital Tuesday and Wednesday, where the Western allies will discuss helping Ukraine to oust Russian occupation forces.

Ukraine is pressing for admission to the military alliance but Biden said in an interview aired Sunday with CNN that this cannot happen until the war is over.
