LONDON — In almost every way, British Prime Minister Keir Starmer will walk into the White House on Thursday as an alien in President Donald Trump’s MAGA universe: a former human rights lawyer, a onetime top prosecutor and, after vanquishing Conservatives in elections last summer, the United Kingdom’s most liberal leader in more than a decade.

In his visit on Thursday, the prime minister will try to leverage the U.K.'s so-called "special relationship" with U.S. and act as a bridge between the Trump administration and U.S. allies in Europe.

U.K. Prime Minister Keir Starmer is backing up other European leader's push to persuade President Donald Trump not to abandon Ukraine in pursuit of a peace deal in the three-year-old war with Russia during his visit to Washington Thursday.
