The UK will supply enriched uranium to Ukraine for its nuclear power stations and impose new sanctions against Russia, British Prime Minister Keir Starmer said ahead of a G7 summit session Tuesday. Denouncing Russia's “barbaric strikes” on Ukraine, the UK is “stepping up” by “choking off the revenues that fuel Putin's war and powering Ukraine through the winters ahead,” his office quoted Starmer as saying, referring to Russian President Vladimir Putin. Some £210 million ($282 million) worth of export finance will allow the UK-based Urenco to supply enriched uranium to Ukraine's nuclear power producer, Energoatom, according to his office. “We will stand with Ukraine for as long as it takes and this announcement reinforces that, Starmer said. Ukrainian President Volodymyr Zelensky was due to attend the summit of seven leading world powers in the French resort town of Evian-les-Bains on Tuesday, dedicated to peace and security in Ukraine and Europe. French President Emmanuel Macron is hoping to persuade his US counterpart Donald Trump to exert more “pressure” on Russia during the G7 summit. He told French broadcaster TF1, “I want the Americans to say: we are with you, we will continue to help Ukraine, and we will increase pressure on Russia. Proper negotiations mean Ukraine and Russia at the table together with Europeans and Americans.”
