The Foreign Office said there had been “a summer of Russian delay tactics at peace talks” aimed at ending the conflict in the region, as well as increased attacks on Ukrainian civilians and infrastructure.

Cooper added support for Kyiv was “unwavering and stronger than ever” and that fresh funding would support Ukraine through the winter and into 2026.

She continued: “Putin’s bombardment of Ukrainian civilians, his stalling and delaying in internationally-backed peace talks, and his blatant disregard for human life must end.”

Of the funding boost, £100 million will be used to help civilians in frontline communities, including to repair critical water and heating systems, support livelihoods and strengthen resilience over the winter.

The remaining £42 million will go towards carrying out vital repairs to Ukraine’s electricity network and putting in place critical protection for gas and power infrastructure.

Cooper will visit Kyiv’s cabinet of ministers government building, which was hit for the first time on Sunday when Russia carried out its largest aerial attack on Ukraine since the war began. She will also visit a residential building destroyed by a Russian strike.

Separately, Prince Harry made a surprise visit to Kyiv on Friday after an invitation by an organisation that supports Ukrainians with life-changing injuries caused by the war.

The Duke of Sussex, who arrived by train on Friday morning, said he wanted to do “everything possible” to help the recovery of injured military personnel.
