58-year-old John Yates, from Warrington, was found guilty in February at Caernarfon Crown Court of the murder of his wife Barbara.
The jury heard Yates had a long history of violence against her.
Today he was sentenced to 18 years for the murder of his 50 year old wife in July last year at an unknown location.
He told the court he covered her in a tarpaulin and drove the body to St Asaph.
Acting Detective Chief Inspector Iestyn Davies said “It is a feature of this case, that Barbara Yates was subjected to domestic abuse at the hands of John Yates on many occasions and tragically found herself unable to break free from this abusive and violent relationship."
