Vincent Tchenguiz and his brother are reputed to own 1% of Britain's property freeholds.
In March 2011, he was arrested in a dramatic - well-publicised - dawn raid in Mayfair, just before he was meant to fly out to the French Riviera to host a glamorous party on his 40 metre luxury yacht.
The Serious Fraud Office accused him of fraudulently obtaining a £100m loan from Icelandic Bank Kaupthing, which had gone bust.
This week, the case against him was dropped.
He gave a rare broadcast interview to Today presenter Evan Davis.
