In pictures: Russian tycoon row

Just who visited Oleg Deripaska's luxury yacht moored in the Ionian Sea and said what to whom is now the subject of much interest.

Russia's richest man, Oleg Deripaska is at the centre of a British political row because of the people he saw on his Corfu holiday.

It was sparked by Nathaniel Rothschild - businessman and friend of shadow chancellor George Osborne - who was holidaying nearby at his family's Corfu estate.

Nathaniel Rothschild told The Times that George Osborne had discussed a donation of �50,000 to the Conservative Party with Mr Deripaska.

Added to the intrigue, the new business secretary Lord Mandelson - a European Commissioner at the time - also spent time on Mr Deripaska's yacht.

It is alleged Peter Mandelson and Mr Osborne met at Agni Taverna in Corfu, Greece, and compared notes on Gordon Brown.

The shadow chancellor denies any donation was sought during the meeting with Mr Deripaska.
