Ukrainian President Volodymyr Zelenskyy visited the United Kingdom on Wednesday, in his first trip to the area since Russia invaded Ukraine on Feb. 24, 2022.

Zelenskyy met with Prime Minister Rishi Sunak at Downing Street, where they posed for a brief photo op outside of the prime minister's home. Zelenskyy is set to address Parliament during his UK trip and will meet with King Charles III later in the afternoon.

The U.K. remains a top contributor to Ukraine amid the ongoing invasion, as it has sent the country more than $2.5 billion in military weapons and equipment.

The contributions include a pledge to send Ukraine Challenger 2 tanks, which British Prime Minister Rishi Sunak announced Saturday, along with additional artillery systems following a call with Zelenskyy.

The two leaders "agreed on the need to seize on this moment with an acceleration of global military and diplomatic support to Ukraine," according to a readout of the call from the British government.

France, Poland, Germany, and the United States have similarly agreed to send tanks.
