British Prime Minister Keir Starmer’s exhortation comes two days after U.S. backing of Ukraine appeared in jeopardy when President Donald Trump lashed out at Ukrainian President Volodymyr Zelenskyy.

British Prime Minister Keir Starmer says Europe must take responsibility for defending itself as world leaders met in London to discuss working together to stop Russia’s war in Ukraine.

Keir Starmer's call for European allies to increase their arms spending was not a sign that he thought the U.S. had become an unreliable ally, he said.

Keir Starmer has said he is ready to put British “boots on the ground” to maintain the peace if a deal is done to end the war in Ukraine. The prime minister said he was working with French president Emmanuel Macron to come up with a plan to present to Donald Trump aimed at finally ending the three-year-long conflict.

Keir Starmer has been joined by Emmanuel Macron, Ursula von der Leyen and other key European leaders as they begin to arrive at Lancaster House for a London summit. The meeting will be the biggest European peace summit since the end of the Second World War.

The leaders of Britain and France are spearheading a desperate diplomatic drive to shore up Europe’s security, bolster Ukraine’s defenses and ensure the Trump administration doesn’t seek a ceasefire on terms that reward Moscow for invading its neighbor.

The Prime Minister warned the West stands at a ‘crossroads in history’ as he announced a missile finance deal with Ukraine.

Starmer tells leaders step up at ‘once in a generation moment’ at Ukraine summit - The Prime Minister said that getting a good outcome for Ukraine is ‘vital to the security of every nation’ at the summit ‘and many others too’.

Ukraine’s president has few options after last week’s astonishing Oval Office row with U.S. President Donald Trump, who berated the wartime leader.
