The UK is hosting a closed meeting of senior military leaders from over 20 countries to discuss plans for a peacekeeping force in Ukraine. Prime Minister Sir Keir Starmer will attend after visiting Barrow to lay the keel of a new nuclear submarine. The meeting will address operational plans for the peacekeeping force, but faces challenges, including opposition from Russian President Vladimir Putin and reluctance from the US for air cover. Starmer emphasizes the importance of defense spending for communities and announces Barrow's new title of 'Royal'.
