Ukrainian President Volodymyr Zelensky arrived in the U.K. on Wednesday for a surprise overseas visit thought to be only his third foreign trip since Russia invaded his country last year. Zelensky addressed the British Parliament, met with Prime Minister Rishi Sunak, and headed to London to greet King Charles III, Buckingham Palace confirmed. Zelensky dressed in his signature deep green sweatshirt, cargo pants and Lowa task force boots to meet the king—a style he’s donned since the war began. A Downing Street press release said Prime Minister Rishi Sunak will commit to another round of military support including fighter jet pilot training and supplying more long-range weapons. The visit to Britain comes after Zelensky’s trip to Washington, D.C., in December and a stop-off in Poland on his way back to Ukraine. He’s expected to address European leaders Thursday after rumors of a visit to Brussels leaked to the press earlier this week.
