ITV’s new documentary about prolific serial killers Fred and Rose West will finally be aired on Thursday 21 February.
Sir Trevor’s documentary is understood to feature an interview with Jayne Hamer, a former lodger to the couple who has never previously told her story.
Fred West took his own life at HM Prison Birmingham on New Year’s Day 1995 but Rose is still alive, now 65 and serving 10 life sentences behind bars after being found guilty of nine murders.
The new one-hour film arrives at a boom time for true crime series.
