Chelsea owner Roman Abramovich has had his assets frozen, a prohibition on transactions with UK individuals and businesses, a travel ban and transport sanctions imposed.
Prime Minister Boris Johnson said: “There can be no safe havens for those who have supported Putin’s vicious assault on Ukraine.
“Today’s sanctions are the latest step in the UK’s unwavering support for the Ukrainian people. We will be ruthless in pursuing those who enable the killing of civilians, destruction of hospitals and illegal occupation of sovereign allies.
Meanwhile, Foreign Secretary Liz Truss said: “Today’s sanctions show once again that oligarchs and kleptocrats have no place in our economy or society. With their close links to Putin they are complicit in his aggression.
“The blood of the Ukrainian people is on their hands. They should hang their heads in shame.
“Our support for Ukraine will not waver. We will not stop in this mission to ramp up the pressure on the Putin regime and choke off funds to his brutal war machine.”
