UK Prime Minister Andy Burnham arrived in Kyiv on Monday for his first foreign visit since taking office and announced the transfer of blueprints for long-range missile components to Ukraine.

The move allows European defense firm MBDA to declassify information on British-made parts used in the Scalp missile, the French version of the UK's Storm Shadow cruise missile. This step enables Ukraine and France to advance plans for local assembly and eventual domestic production of the weapons.

Burnham, who chairs the first meeting of the coalition of the willing during the trip, stated that the UK stands with Ukraine "today and for as long as it takes." He described Ukraine's security as Britain's security and accepted an award on behalf of the British people for prior support.

The Scalp missile can strike targets up to about 150 miles into Russia. The decision builds on earlier UK supplies of Storm Shadow missiles and follows France's agreement last month to share its Scalp blueprints.

Russian officials condemned the development, claiming it adds fuel to the conflict and hinders peace efforts. The visit coincides with Ukraine's 35th Independence Day celebrations.

Defense Minister Luke Pollard emphasized the need to help Ukraine defend against Russia's illegal invasion, which has targeted civilian areas including shopping centers and housing.

The agreement marks a significant technology transfer that strengthens Ukraine's capacity for precision strikes without relying solely on foreign supplies.
