U.S. President Joe Biden and British Prime Minister Rishi Sunak on July 10 reaffirmed their “steadfast support” for Ukraine as they discussed the upcoming NATO summit, the White House said. Biden met with Sunak in London on the first stop in his current three-nation trip. Biden and Sunak also discussed the Atlantic Declaration, a trade and economic partnership initiative launched in June, and developments in Northern Ireland. The U.S. president is due to meet with King Charles later on July 10 before traveling to the NATO summit in Vilnius, Lithuania, where allies are expected to show solidarity with Ukraine.
