Burnham told Zelenskyy the U.K. will continue to develop innovative military solutions for use on the battlefield in Ukraine — including retrofitting British capability onto equipment gifted from other partners, the spokesperson said. He also pledged to continue diplomatic efforts on international supplies of defensive equipment.

In an earlier interview with the broadcaster Piers Morgan, Zelenskyy said Trump’s deal with Russia meant he is “not the right side of history” and said Ukraine is “losing a strong partner.”

He said there had been a deliberate decision by Elon Musk’s SpaceX and the U.S. to block access to the satellite system Starlink, warning “this decision will bring a lot of human losses. Of course, people will die.”

Burnham has so far refused to condemn the U.S. president for making a deal with Russia, telling MPs Wednesday he wants to “try and repair bridges so that the support comes back.”

In an overnight statement issued by No. 10 ahead of the visit, Burnham said: “Our rock-solid support to Ukraine is vital for keeping us safe here in the UK and ensuring those on the frontlines have the equipment they need to push back Russia.

“My message to the Ukrainian people could not be clearer, we are with you for as long as it takes, and we will go further and faster in our support to back your courageous fight for peace in Europe. It is not just the right thing to do, but it’s the necessary thing to do. Russia’s aggression cannot be allowed to succeed on our continent.”
