Writing on the X platform, Mr Zelensky said: "London. A meaningful and warm meeting with Prime Minister Sir Keir Starmer.

"During our talks, we discussed the challenges facing Ukraine and all of Europe, coordination with partners, concrete steps to strengthen Ukraine’s position, and ending the war with a just peace, along with robust security guarantees.

"A principled statement of support from the Prime Minister and an important decision: today, in our presence, Ukraine and the United Kingdom signed a Loan Agreement.

"This loan will enhance Ukraine’s defence capabilities and will be repaid using revenues from frozen Russian assets. The funds will be directed toward weapons production in Ukraine. This is true justice – the one who started the war must be the one to pay.

"I thank the people and government of the United Kingdom for their tremendous support from the very beginning of this war. We are happy to have such strategic partners and to share the same vision of what a secure future should look like for all."
