The leaders of Britain, Canada, France, Germany, Italy, Japan and the United States also agreed on a final statement that included references to the Ukraine war, in a contrast to last year’s meeting, when Trump walked out early.

“It was tough work but worth it,” said German Chancellor Friedrich Merz, describing the statement as a “success”.

As well as increasing supplies of air defence equipment to Ukraine, the leaders agreed to “increase the pressure on the Russian war economy” by strengthening sanctions, including on Moscow’s fossil fuel revenues, the statement said.

French President Emmanuel Macron hailed a “very deep change in the US approach” towards Ukraine, saying Trump had understood that Russia’s Vladimir Putin was not interested in peace.

“President Trump, like all of us, simply acknowledged that there was no serious willingness on Russia’s part today to discuss peace.”
