UK Foreign Secretary David Lammy has emphasized the need for "nerve and guts" in ongoing discussions with the White House regarding the potential use of Storm Shadow missiles by Ukraine within Russian territory. His comments appear to be directed at the Biden administration, urging allies of Kyiv to demonstrate resolve during this critical time. This statement comes shortly after Lammy and Labour leader Keir Starmer met with President Joe Biden at the White House, where they were unable to reach an agreement on this contentious issue. The negotiations remain a significant point of contention between the UK and the US as they navigate the complexities of supporting Ukraine in its conflict with Russia.
