Zelenskyy arrived to shouts of support from people who had gathered outside of 10 Downing Street, where Starmer gave him a hug and ushered him inside.

“And as you heard from the cheers on the street outside, you have full backing across the United Kingdom,” Starmer told the leader of the war-torn country.

“We stand with you, with Ukraine, for as long as it may take.”

Zelenskyy thanked him and the people of the UK for their support and friendship.

The meeting comes the day after an extraordinary diplomatic meltdown when Trump and Vice President JD Vance blasted Zelenskyy in the Oval Office on live television for not being grateful enough for US support.

Zelenskyy had been poised to ink a deal to give the US access to mineral riches as Trump pressures Ukraine to reach a deal to end the war with Russia. But he left town without signing anything.

Zelenskyy had been scheduled to meet with Starmer on Sunday before a summit with other European leaders to discuss Ukraine and shoring up defenses across the continent.

But the timetable for their bilateral meeting was apparently sped up in the aftermath of the Washington visit.

Zelenskyy will meet with King Charles III on Sunday before the summit that is being held at Lancaster House, a 200-year-old mansion near Buckingham Palace.
