UK Prime Minister Keir Starmer says he will push for fresh sanctions aimed at reducing Russian revenue and disrupting the “shadow fleet” of vessels supporting Moscow’s war effort. Speaking as he arrives in France for the G7 summit, Starmer frames Russia’s actions as a threat to European security and says the goal is to “choke off” funding channels used by Russia, including targeting financial networks linked to the shadow fleet.

Alongside the sanctions push, Starmer pledges energy support for Ukraine, including nuclear-related assistance and broader power measures. The plans are presented as part of efforts by G7 leaders to sustain support for Ukraine over the long term. Multiple outlets report that Starmer tells the summit that the group is determined to stand with Ukraine for as long as needed.

The reporting also references earlier related UK actions involving Russian shadow fleet shipping, reflecting wider pressure in Europe on enforcement against vessels and intermediaries linked to sanctioned Russian trade. The G7 meeting in Évian-les-Bains is positioned as the forum where Starmer seeks agreement on the next round of measures.
