Talks have been completed between Biden and Starmer. One of the topics rumoured to have been discussed was the possible lifting of restrictions on the Storm missile.
The decision will never be made public, and presumably before a final decision, one way or the other is made other NATO countries will voice their opinions about Zelenskyâs use of the missile to take out military installations within Russian territory.
Below is listed detail of the missile
What are Storm Shadow missiles, and why does Ukraine want them
Storm Shadow missiles can hit targets up to 155 miles (250km) from their launch site â meaning they could strike deep into Russian territory. They are powerful enough to penetrate bunkers and ammunition stores and damage airfields, and can be precisely targeted.
They were developed in an Anglo-French collaboration, and manufactured by a joint venture also involving Italy, using components supplied by the US. Consequently, all four countries would have to sign off on any change to the conditions attached to their use, even if they are not the direct suppliers themselves.
Why has the west not allowed Ukraine to use the missiles in Russia
Throughout the war, the US and its allies have sought to strike a balance between giving Ukraine the weapons it needs to defend itself while avoiding any move that could be viewed as a provocation and lead to direct involvement in the war.
What has changed
Several factors. Ukraine is facing a lot of pressure on the frontline, and fears a difficult winter ahead. Its surprising cross-border incursion into Kursk last month has reframed thinking on the use of weapons on Russian soil and acted as a reminder that Ukraine is at its most effective when it is changing the dynamic of the conflict.
What are the benefits and risks of allowing Storm Shadow to be used within Russia
There is an inherent tension in how Ukraine believes the weapons can be effective: by degrading Russiaâs ability to strike against targets in Ukraine, but also by bringing the war further on to Russian soil, in theory thereby making the costs to Putin more acute.
Despite having lost between 68,000 and 150,000 soldiers, according to some estimates, and with hundreds of thousands more wounded, Putin does not appear to have paid any significant political cost. Making ordinary Russians more fearful of the consequences of the war in Ukraine might make him pay more attention. But that is a narrow tightrope to walk.
A strike that caused many civilian casualties could be very problematic for the west, and if it was caused by a Storm Shadow missile it would be very hard to deny western involvement.
