Foreign Office also says it plans to extend sanctions to Russian-controlled territories of Donetsk and Luhansk
Staff and crew who work on yachts or planes owned by Russian oligarchs could face UK sanctions under a move by the Foreign Office to extend the penalties.
The aim is to make it harder for yachts to be maintained by crew, sometimes indirectly owned by oligarchs, and covers anyone providing technical assistance and maintenance of a yacht or plane. It will also restrict the ability of oligarchs to find staff willing to sail or fly their assets out of the UK jurisdiction.
