British prosecutors have reversed their position and say they will charge a former lawmaker who now has severe dementia with sex crimes against children.

The Crown Prosecution Service said Monday that a "trial of the facts" would be held for 86-year-old Greville Janner.

Police and child abuse victims expressed outrage when prosecutors announced in April that they would not charge Janner over alleged offenses against boys, even though there was enough evidence to prosecute. Prosecutors said his dementia meant he was not fit to stand trial.

But after his alleged victims complained, prosecutors decided "it was in the public interest to bring proceedings before the court."

Janner was a Labour Party lawmaker from 1970-97, later serving in the House of Lords. His family says he is innocent.
