Rishi Sunak meets Volodymyr Zelenskiy in surprise visit to Ukraine

Following in the footsteps of Boris Johnson and Liz Truss, Sunak has pledged that UK support for Ukraine in the fight against Russia will remain steadfast.

He laid flowers at a memorial for the war dead in Kyiv and lit a candle at a memorial for victims of the Holodomor famine, before meeting emergency personnel at a fire station.

The visit comes as Kyiv and several other regions of Ukraine grapple with power shortages after relentless Russian attacks on critical infrastructure.

As temperatures fall below freezing and the first snow of the season dusts the streets of Kyiv this week, people across Ukraine are starting to worry about how to heat their homes due to blackouts caused by the Russian bombardment while officials struggle to restore power nationwide.

Videos circulated on Russian social media this week purporting to show the bodies of Russian servicemen apparently killed after having surrendered to Ukrainian troops.

In the footage, the soldiers, who are giving themselves up, lie down on the ground in the debris-filled back yard of a house before the video abruptly cuts off as shots are heard.

More footage shows the bodies of around a dozen people surrounded by apparent bloodstains.
