The UK government announced on Tuesday that it had imposed sanctions on two former members of the board of the Rosneft oil company: Didier Casimiro and Zeljko Runje.
Both are now subject to asset freezes for "benefiting from or supporting the Russian government by serving as a manager of an entity affiliated with the Russian government".
This is the latest addition to a long list of sanctions imposed by the UK after the war in Ukraine.
