A US prosecutor has said OJ Simpson was fairly convicted of armed robbery and kidnapping, responding to the American football legend’s appeal in a sports memorabilia case.

Four men who took plea deals and testified against OJ Simpson are scheduled to be sentenced four days after the former football star and a co-defendant learn their fate.

An all-white jury was chosen to judge OJ Simpson and a co-defendant on kidnapping and robbery charges after a contentious courtroom battle in which defence lawyers argued African-Americans were being systematically excluded by the prosecution.
