In response to accusations of espionage, Russia has expelled six British diplomats, which the UK Foreign Office denies. Meanwhile, UK Prime Minister Sir Keir Starmer is in Washington to meet President Biden, where they will discuss potential changes to Ukraine's military capabilities, particularly regarding the use of long-range missiles against targets in Russia. This meeting follows a warning from Vladimir Putin that allowing such strikes could mean NATO is at war with Russia. Starmer emphasized that Russia initiated the conflict and that Ukraine has the right to self-defense. The UK has provided Storm Shadow missiles to Ukraine, which could be used for cross-border attacks if restrictions are lifted, a decision that remains under discussion. Concerns persist among US and European officials about potential Russian retaliation if these missiles are used.
