Ian Stewart has been sentenced to a whole-life jail term for murdering his wife six years before he went on to kill his new fiancée.
The 61-year-old will die behind bars after a judge handed him the UK's most severe punishment for his heinous crimes.
In 2016, Stewart killed his fiancee, 51-year-old children’s book author Helen Bailey, before dumping her body in a cesspit at the £1.5 million home they shared in Royston in Hertfordshire.
