The UK Government has announced a major new package of sanctions against Russia, becoming the first country to impose restrictions on all ten of the country’s largest oil producers, according to Downing Street. The measures, announced on 12 November 2026, aim to restrict energy revenues available to Russia as Britain and its European allies seek to increase pressure on Moscow to end the war in Ukraine.
Slavneft completes sanctions coverage
The latest measures include Russian oil producer Slavneft, completing UK sanctions coverage of Russia’s ten largest oil producers, according to the Government. Earlier British measures had already targeted major energy companies including Rosneft, Lukoil and Transneft. Downing Street says the measures now reach across much of Russia’s energy revenue chain, including producers, trading networks, supply chains and vessels.
Vostok Oil and shadow fleet vessels targeted
The package also targets Rosneft’s flagship Arctic oil and gas project, Vostok Oil, major Russian coal companies and vessels involved in transporting Russian oil and liquefied natural gas. The Government says the aim is to make it harder for Russia to generate income from energy exports. The financial impact of these designations has not yet been quantified.
Announcement at European summit
Prime Minister Andy Burnham announced the measures as European leaders gathered at the European Political Community summit in Dublin. He called for sustained pressure on Moscow following peace negotiations involving Ukraine and Russia in Abu Dhabi. Downing Street said Britain would continue pressing for a full and immediate ceasefire, European participation in negotiations and legally binding security guarantees for Ukraine.
Official sanctions register updated
The Foreign, Commonwealth and Development Office updated its Russia sanctions register on 12 November. The official update records 11 new designations, nine new vessel specifications and one variation. Sanctions are legal restrictions, but their practical effect depends on enforcement, international cooperation and trading arrangements. No official estimate has been published of how much revenue this particular package will deny Russia.
What happens next?
The Government argues that targeting energy production and shipping together will increase economic pressure on Moscow. Whether the new restrictions materially affect Russia’s finances or negotiating position remains to be seen. The UK’s claim to be the first country to sanction all ten leading producers is attributed to Downing Street.
