Oligarch renounces Russian citizenship over Ukraine war

The billionaire banker and entrepreneur Oleg Tinkov has renounced his Russian citizenship because of the conflict in Ukraine, which he has previously criticised.

He has also been targeted by British sanctions imposed soon after the conflict began in late February.

He was previously arrested in London in 2020 on charges of tax evasion in the United States. He was later released on bail and treated for leukaemia in London.

He quit his role as CEO of Tinkoff in 2020 and the bank has distanced itself from his comments.
