His defence lawyers had previously argued that two previous investigations found he had no case to answer and there was insufficient evidence to warrant a trial.

They have also contested the suggestion that Ganic was in charge at the time of the attacks.

Ganic was arrested at Heathrow Airport on March 1 as he attempted to leave Britain after attending a degree ceremony at the University of Buckingham.

Serbia has said Ganic and a number of other people are suspected of war crimes, and blames them for the 1992 attack on a Yugoslav convoy in Sarajevo, when more than 40 soldiers were killed.
