The sentence places Ali alongside some of Britain's most notorious murderers, including Sarah Everard's killer Wayne Couzens, child serial killer Lucy Letby and MP Sir David Amess's murderer Ali Harbi Ali. Who else is serving whole-life orders? Whole-life orders are the most severe punishment available in the criminal justice system. The sentence can only be imposed by a judge in exceptionally serious cases, such as multiple murders, child murders involving abduction or sexual abuse, or acts of terrorism causing mass loss of life. Only four women have ever received whole-life orders: Lucy Letby, Rose West, Joanna Dennehy and Moors murderer Myra Hindley, who died in prison in 2002.
