[GB-RUS] UK sanctions relating to Russia JSON

Targets individuals and entities involved in destabilising Ukraine or in obtaining a benefit from or supporting the Russian government. Designated persons are subject to an asset freeze, and designated individuals to a travel ban. Designations sit alongside country-wide restrictions on Russia, including bans on the export of military, dual-use, critical-industry and luxury goods, import bans on oil, gold, diamonds, and iron and steel, capital-market, lending and correspondent-banking prohibitions, a ban on providing professional and business services, and the closure of UK ports and airspace to Russian ships and aircraft. Some named entities face sectoral financial and investment restrictions rather than an asset freeze.
