Kiranjit Uppal, an Indian-origin man, is scheduled to face trial from September for the killing of Harminder Singh Jhagra during a major group clash in Hayes, west London, in February 1996.
Uppal (36) was arrested by the police in September last year when he arrived at the Heathrow airport from India.
He was charged with murder and grievous bodily harm, but in court pleaded not guilty to killing Jhagra, who was 28 at the time of his death. Uppal also pleaded not guilty to attacking another man, Jagwinder Randhawa.
Jhagra suffered serious injuries when he was knifed in the arm, which severed an artery, during the clash, and was declared dead in hospital.
Uppal's trial is scheduled to begin on September 1 and is expected to last four weeks.
