Ratko Mladic has appealed for a six-month delay in the start of his Yugoslav war crimes trial, saying delays by prosecutors in disclosing evidence could lead to a miscarriage of justice.

A motion filed Monday by lawyers for the former Bosnian Serb military commander is his latest attempt to delay his trial. Last week he also sought a postponement, asking for the Dutch presiding judge to be replaced.

Mladic's trial is to start Wednesday. He faces 11 charges alleging that he orchestrated atrocities by Serb fighters throughout the 1992-95 Bosnian War.

Mladic has refused to enter pleas but denies wrongdoing.

The 70-year-old former general was arrested last year in Serbia after 15 years as a fugitive. He is the last major player from the Bosnian conflict to go on trial at the UN court.
