The 45-year-old and his partner Gemma Watts, 49, have admitted murder and perverting the course of justice by dismembering Ms Mayhew’s body, distributing the parts at “various locations” and cleaning up the scene, the Old Bailey heard.

Builder Steve Sansom was out of prison on life licence for another murder when he killed Sarah Mayhew, 38, and dumped her remains in Rowdown Fields, New Addington, south London, last spring.

A builder who committed the "bloodthirsty" murder of a 38-year-old woman and then dismembered her body has been jailed for the rest of his life. Steven Sansom, 45, from Sutton, was handed a whole-life order at the Old Bailey on Thursday after pleading guilty to the murder of Sarah Mayhew last year and perverting the course of justice - meaning he will never be released from prison.
