British Prime Minister Rishi Sunak promised Ukraine 50 million pounds for defense during a meeting with President Volodymyr Zelenskiy during his first visit to Kiev as head of government.

Since the first days of the war, Ukraine and Britain have been the strongest allies, Zelenskiy said after the meeting.

The aid package is designed to counter air attacks. The £50 million defense aid includes 125 anti-aircraft guns and technology to counter drones, including dozens of radars and drone countermeasures, the BBC reported.

Sunak also announced that Britain would expand its offer to train Ukraine's armed forces by sending experienced army medics and engineers to the region to provide specialized support.
