The trial of a British man accused of causing the death of a compatriot in a fight during an island holiday has been postponed.
Andrew Symeou, from Enfield, north London, is accused of punching Jonathan Hiles off a platform in a nightclub on the island of Zakinthos in July 2007.
Mr Hiles, from Cardiff, later died of his injuries.
Mr Symeou denies he was in the club. He has been charged with causing fatal bodily injuries, an offence with a minimum five-year sentence.
A court in the western Greek city of Patras was due to hear testimony from defence witnesses in the case.
Friends of Mr Hiles testified earlier this week, and identified Mr Symeou as the man who had punched Mr Hiles. Mr Symeou's defence lawyer, Giorgos Pyromallis, is disputing the claim.
On Friday, Mr Pyromallis said he had brought perjury suits against two of Mr Hiles' friends who testified, and intended to do the same for another three.
The trial was postponed until April 19.
It has already been postponed several times for various reasons, including a lawyers' strike, a request by a lawyer for Mr Hiles' family for more time to review the case and a defence request for a new interpreter.
Mr Symeou was extradited to Greece to stand trial over Mr Hiles' death in 2009. He was held in pre-trial detention for 10 months before being granted bail.
