London and Brussels must play "a full part" in providing security guarantees for Kiev, the UK prime minister has said

The UK and EU must be involved in a peace settlement in Ukraine, which includes putting boots on the ground, British Prime Minister Keir Starmer has said following talks with US President Donald Trump in Washington. The US has recently initiated peace talks with Russia, sidelining both the EU and UK.

Starmer met with Trump at the White House on Thursday, where they discussed a plan to reach an enduring peace in Ukraine.

"The European countries, including the United Kingdom, need to play a full part in that," Starmer said in an interview on Fox News.

London will play "a leading part," he insisted, whether it's "troops on the ground... or possible air, maritime work" together with the EU. The UK and France have previously said they are prepared to deploy peacekeeping troops to Ukraine to secure any peace deal with Russia.

Trump has indicated, however, that Washington has no plans to send US forces to support a European-led peacekeeping mission, arguing that Russian President Vladimir Putin can be trusted to not breach the eventual agreement.

Moscow has opposed the deployment of unauthorized troops to Ukraine, warning that without a UN mandate, they would be considered legitimate targets.

Russian Foreign Minister Sergey Lavrov has said the idea of deploying foreign troops to Ukraine is being pushed primarily by France and Britain, suggesting that this is meant to "further fuel the conflict and stop any attempts to cool it down." The Foreign Ministry also accused the EU and UK of embarking "on a path of militarism."

Britain has been a steadfast supporter of Ukraine since the conflict escalated three years ago, providing substantial military aid and implementing stringent sanctions against Russia. As of February, London has committed nearly $10 billion in military assistance to Kiev.
