YAOUNDE, August 20, 2008 (AFP) - The trial of Cameroon's main opposition leader John Fru Ndi, charged with complicity in the killing of a party activist, has been put back to Octoer 13, a judicial official said Wednesday.

Fru Ndi, who denies the allegation, is accused of involvement in the May 2006 death of Gregoire Diboule Nzali when rival factions of his Social Democratic Front clashed at its Yaounde provincial headquarters.

Twenty-two others are charged in the same case.

Fru Ndi founded the Social Democratic Front -- which draws much of its support from anglophone parts of Cameroon -- in 1990 in opposition to the governing Cameroon People's Democratic Movement led by President Paul Biya.
