A brother of fugitive drug lord Tony Mokbel has pleaded guilty to drug trafficking at Melbourne County Court.

Kabalan Mokbel, 45, was arrested in Melbourne on April 11, 2003, after detectives from the Victoria police Purana task force found a stash of methamphetamine in his car.

Mokbel, a truck driver from suburban Brunswick, appeared before Melbourne's County Court on Monday, pleading guilty to one charge of trafficking a drug of dependence.

Judge Philip Coish adjourned the matter to November 12 for a pre sentence hearing and remanded Mokbel in custody.

His brother Tony is in jail in Greece awaiting extradition to Australia after skipping the country last year near the end of his trial for trafficking cocaine.
