An MPs' report into abuse allegations at Deepcut barracks in Surrey has criticised the Army of failing in the way it handles new recruits and allowing bullying to go unreported.
The Army says the Deepcut deaths were suicide
The key events in the case follow:
June 1995 - Private Sean Benton, of Hastings, East Sussex, is found dead at the Princess Royal Barracks, Deepcut, with five bullet wounds to his chest. Despite ballistics tests suggesting only one bullet was fired from close range and the others from a distance, the Army says he committed suicide.
