British Prime Minister Keir Starmer arrived in Ukraine’s capital on Thursday with a pledge to help guarantee the country’s security for a century, days before Donald Trump is sworn in as U.S. president.

Struck by the “grim reminder” of war while visiting a burns hospital unit in Kyiv earlier today, the prime minister promised the UK would “play its full part” in guaranteeing Ukraine’s security. The Sheffield-made guns will be delivered to Ukraine’s military over the next few weeks as part of this deal, Sir Keir said.
