Killer taxi driver Christopher Halliwell faces a whole life order when he is sentenced on Friday for his second murder.

On Monday a jury found the 52-year-old guilty of murdering Becky Godden following a two-week trial in which he represented himself.

Halliwell is already serving a life-sentence for the murder of 22-year-old Sian O'Callaghan, who he abducted in his taxi as she made her way home from a night out in Swindon in March 2011.

Halliwell confessed to killing Ms O'Callaghan and took police to her body before offering "another one" and leading them to where he had buried missing sex worker Becky Godden several years earlier.

However, he later denied the murder of Becky Godden and it took a jury at Bristol Crown Court less than three hours to find him guilty.

As the jury returned their verdict Halliwell smirked at Ms Godden's family.

Retired High Court judge Sir John Griffith Williams branded father-of-three Halliwell a liar and told him he faced either a whole life order or a "significant" minimum term of imprisonment.

A High Court judge initially ruled Halliwell's confessions could not be used as Detective Superintendent Steve Fulcher had breached police guidelines on interviewing suspects.

The charge of murdering Miss Godden was withdrawn until March this year following an investigation by Wiltshire Police that uncovered overwhelming evidence against Halliwell.
