The UK's Prime Minister Keir Starmer said after Friday's meeting with US President Joe Biden that the two had a broad discussion about the strategy regarding Ukraine, but that it was not a conversation that revolved around "a specific capability".
Prior to the conversation, reports emerged that Starmer planned to pressure Biden to support his plan to allow cruise missiles of the Storm Shadow type, which the British have sent to Kiev, to be fired deep into Russian territory.
However, according to the Labour leader, the issue is expected to be discussed further in connection with the UN General Assembly meeting in New York next week, together with a "wider group of individuals".
Biden has been restrictive regarding approval. However, reports that Russia is receiving new deliveries of drones and robots from Iran have made the issue of expanded possibilities for Ukraine to use long-range missiles more pressing.
On Thursday, Russian President Vladimir Putin warned that a green light for Ukraine to strike with advanced weapons against targets deeper in Russia would mean war with NATO. "It would fundamentally change the conflict", according to Putin.
