WASHINGTON (AP) — British Prime Minister Keir Starmer is using a visit to Washington to press President Donald Trump not to abandon Ukraine as he looks to find a quick endgame to Russia’s bloody invasion of its neighbor. With a mix of flattery and frank talk, the center-left Starmer made the case to the Republican president to remain cautious as he goes about ending the biggest conflict in Europe since World War II. The British premier started the visit by delivering an invitation from King Charles III to come to Scotland for a “historic” state visit — noting it was an “unprecedented” honor since Trump already had been given the royal treatment by Queen Elizabeth II during his first term.
