The Serious Fraud Office (SFO) has notified property investor Vincent Tchenguiz that he is no longer a suspect in relation to the 2008 collapse of Icelandic bank Kaupthing, bringing to an end a long-running investigation that has threatened the reputation of the UK fraud agency.

The news, which was delivered to Tchenguiz yesterday (18 June), comes after Tchenguiz (pictured) and his brother Robert became the centre of an investigation into the collapse of Kaupthing over two years ago.
