Russian President Vladimir Putin cannot be allowed to “play games” over the US-backed ceasefire proposal in Ukraine, Britain’s Prime Minister Keir Starmer said ahead of a key summit of European leaders.

The UK PM is hosting the virtual meeting of the "coalition of the willing" to support a future ceasefire deal.

Russia's president says he supports the idea of a ceasefire in Ukraine, "in principle." But Vladimir Putin has attached various conditions to his agreement — which critics say reveal Russia’s true aims.

Trump has turned American foreign policy on its head since the start of his second presidential term in January. This was highlighted by the public spat with Ukrainian President Volodymyr Zelensky in a televised press meeting, which ultimately ended with Trump pausing military aid to Ukraine.

Vladimir Putin said Ukraine must surrender after President Donald Trump urged the Russian leader to spare the lives of Ukrainian soldiers, following ceasefire talks between the U.S. and Russia in Moscow.
