A new documentary by the BBC has claimed that Roman Abramovich cheated the Russian Government out of £2billion and was investigated for fraud by his country's Department of Economic Crimes.
Abramovich was pictured at a VIP lounge in Tel Aviv airport shortly before his private jet took off for Istanbul after Israel said it was not a haven for sanctioned Russians.
A photograph obtained by Reuters on Monday afternoon showed Abramovich, owner of Chelsea Football Club, sitting in the lounge with a face mask pulled down over his chin.
He was pictured for the first time since he was subjected to sanctions as a result of Russia's war on Ukraine.
The picture was taken shortly before a jet linked to him took off for Istanbul, but it was not immediately clear whether he boarded the flight.
