LONDON — Ukrainian President Volodymyr Zelenskyy will be in London Wednesday to meet the U.K. prime minister and King Charles III as Britain announces new training programs for fighter pilots and marines.

Zelenskyy’s surprise trip includes a visit to see Ukrainian troops being trained by the British armed forces and an address to the U.K. parliament. He will be granted an audience with the British monarch at Buckingham Palace Wednesday afternoon.

This is Zelenskyy’s second trip overseas since Russia invaded Ukraine in February 2022. The Ukrainian leader had also been expected to visit EU leaders in Brussels later this week, but that stop has been cast in doubt after the plans leaked on Monday.

In a statement Wednesday, Prime Minister Rishi Sunak announced the U.K. will now train pilots on the operation of NATO-standard fighter jets as well as marines. This comes in addition to an expansion of U.K. training Ukrainian recruits from 10,000 to 20,000 soldiers this year.

The new training programs show Britain’s commitment “to stand shoulder-to-shoulder with Ukraine for years to come,” Sunak said.

During their talks, Sunak is expected to offer the Ukrainian president longer-range weapons and his backing for Zelenskyy’s plans to work toward peace, No. 10 Downing Street said.

“President Zelenskyy’s visit to the U.K. is a testament to his country’s courage, determination and fight, and a testament to the unbreakable friendship between our two countries,” Sunak added.

The U.K. will also announce further sanctions Wednesday in response to Russia’s continued bombardment of Ukraine, the prime minister’s office said.
