Sir Keir Starmer is heading to Ukraine with Emmanuel Macron and Friedrich Merz as they continue to pressure Vladimir Putin into agreeing a 30-day ceasefire.
The leaders of the UK, France, and Germany are heading to Kyiv in what will be the first time the world leaders have convened in the Ukrainian capital since Russia launched its invasion in February 2022.
Polish Prime Minister Donald Tusk will also meet the group for talks with Ukrainian President Volodymyr Zelensky as a faction of the 'coalition of the willing' ramps up its efforts to halt Russia.
In a joint statement issued before the visit, the leaders of Europe's four major military powers accused Putin of 'obstructing efforts to secure an enduring peace'.
Their statement read: 'Alongside the US, we call on Russia to agree a full and unconditional 30-day ceasefire to create the space for talks on a just and lasting peace,' the leaders said in a statement ahead of the visit.
