Roman Abramovich's luxury estate on the Caribbean island of St Barts and his £90m chateau are among the latest assets to be seized by the authorities.
The Chelsea owner is among several Russian oligarchs to be sanctioned by France. Several governments, including Boris Johnson's cabinet, have sanctioned Abramovich in recent weeks for allegedly having ties to Vladimir Putin, something which he denies.
Russian president Putin is currently waging a bloody and unprovoked war in neighbouring Ukraine. Abramovich is taking part in peace talks and was reportedly poisoned at a meeting last month, suffering peeling skin and temporary blindness, with Russian hardliners said to be those behind the alleged attack.
