British Prime Minister Sir Keir Starmer has held talks with Volodymyr Zelenskyy in Downing Street, as the Ukrainian president seeks to shore up European support for his country's war effort.
Zelenskyy said he would share details of his "victory plan" during the meeting, while Sir Keir pledged his "continued commitment and support" for Ukraine.
The meeting comes as the conflict with Russia heads into its third winter and amid the prospect of Donald Trump, who is widely considered to be less supportive of Ukraine, winning the US presidential election in November.
Mark Rutte, the new head of the NATO military alliance, also attended Downing Street to take part in the talks with Zelenskyy.
The NATO chief held a one-to-one meeting with the prime minister, while Zelenskyy will is expected to travel to France and Italy to continue his European diplomatic tour.
“Let me also make use of this occasion to say that the annual nuclear exercise, Steadfast Noon, will start on Monday. We will have more than 60 aircraft involved in training sessions. The whole exercise will particularly focus on the United Kingdom, the North Sea, but also Belgium and the Netherlands. And in an uncertain world, it is vital that we test our defence and that we strengthen our defence so that our adversaries know that NATO is ready and is able to respond to any threat", Rutte said during remarks.
