Roman Abramovich has hit the headlines since the beginning of Russia's invasion of Ukraine.
The Chelsea Football Club owner came under scrutiny for his alleged connections with Russian President Vladimir Putin, which led to the UK government freezing his assets, including property, artworks and Chelsea FC.
Born in Saratov in south-western Russia in 1966, Mr Abramovich became an orphan at a young age after his mother, Irina, died of blood poisoning when he was just one, followed by his father, who died two years later after an accident with a construction crane.
