Court battle over Picasso art exposes offshore finances of Farage’s billionaire Davos sponsor

Exclusive: Sasan Ghandehari reluctant to share details of $10bn trust in row with Christie's auction house

A high court battle over a Picasso painting has shone a light on the offshore financial structures of an Iranian-born businessman who paid for Nigel Farage's 50,000 trip to Davos.
