A man has been jailed for life for battering his partner to death in a ferocious and merciless attack.
Jonathan Campbell, 37, subjected mum Helen Bannister to years of terror before beating her at their home in Swansea on 1 December last year.

Campbell, of Mayhill, pleaded guilty to murder at Swansea Crown Court having claimed he had snapped after accusing Ms Bannister of cheating on him.
The couple had been in a relationship for five years and the court heard Campbell had a history of violence again women having faced three previous abuse charges, including a case of battery involving Ms Bannister in 2017.
