UK Prime Minister Sir Keir Starmer is due to speak to European allies as he continues his efforts to reach an agreement on Ukraine.

His Defence Secretary John Healey has just returned from Washington DC, where he met with his US counterpart Pete Hegseth to discuss ending Russia’s war on Ukraine.

Addressing Hegseth, he said: “You challenged us to step up on Ukraine, on defence spending, on European security – and I say to you that we have we are and we will further.”

Hegseth said UK leadership was “critical” adding that “European leadership of Nato, led by the UK and others is we believe the future of defence on the continent”.

The US has also paused military aid to Ukraine and stop sharing intelligence as it reviews “all aspects of this relationship”.

In a televised speech, French President Emmanuel Macron said “I want to believe the US will stay at our side, but we must be ready if that is not the case.”

On Thursday, EU leaders agreed a €800bn (£670 bn) boost to defence spending – a move European Commission president Ursula von der Leyen said would help put Ukraine “in a position to protect itself and push for lasting peace”.

The UK and France have said they are willing to provide peacekeeping troops to Ukraine and are urging other European countries to join what they have called a “coalition of the willing”.

According to UK officials about 20 countries are interested in joining the coalition, although would not necessarily offer to send troops, but instead provide other support.

But Sir Keir has said that in order to be effective their presence in Ukraine must be backed by security guarantees from the US.

US President Donald Trump has so far avoided committing to such support, instead arguing that the presence of American workers in Ukraine as part of a potential minerals deal, would be sufficient to deter Russia from further invading Ukraine.

Russia has flatly rejected such a move saying it would amount to “direct, official and unveiled involvement of Nato members in the war against Russia”.

Talks between the US and Ukraine aimed at reaching an agreement will take place next week in Saudi Arabia.

Speaking in Washington, Healey said: “It’s a lasting, secure peace that we all want to see. We’ve got a big role to play in Europe and we are determined to do that.”

Hegseth dismissed as “garbage” suggestions that under Trump’s leadership the US was becoming “pro-Russia”.

He said the president was “working with both sides in a way that only President Trump can”.

Progress towards an agreement appeared to take a step back after Trump and Zelensky had a dramatic row in front of cameras in the Oval Office.

However, Hegseth said the US president was “very encouraged by the signs we’re seeing” from Ukraine.

On Thursday the UK’s Ministry of Defence signed a £30m deal with an Anglo-American firm to provide Ukraine with Altius 600m and Altius 700m systems, designed to monitor an area before striking incoming targets.

Chancellor Rachel Reeves also announced a £2.26bn loan to Ukraine, funded by seized Russian assets.
