The UK government has sanctioned Russian oligarch Roman Abramovich, freezing his assets, including English Premier League soccer club Chelsea.
In a statement Thursday, the UK government said Abramovich has had "his assets frozen, a prohibition on transactions with UK individuals and businesses, a travel ban and transport sanctions imposed."
Abramovich and Putin ally Igor Sechin are among seven oligarchs and politicians to be added to the UK's sanctions list.
The sanctions are estimated to be worth close to $20 billion (£15 billion), the UK government said.
Seven further oligarchs and politicians are being added to its sanctions list, including:
Roman Abramovich, owner of Chelsea FC and has stakes in steel giant Evraz and Norilsk Nickel
Oleg Deripaska, who has stakes in En+ Group
Igor Sechin, the chief executive of Rosneft
Andrey Kostin, chairman of VTB bank
Alexei Miller, CEO of energy company Gazprom
Nikolai Tokarev, president of the Russia state-owned pipeline company Transneft
