The trial of a man who handed himself in to North Wales police having driven from his Warrington home to St Asaph with the body of his estranged wife has started in Caernarfon Crown Court today.
John Yates, 58, admits manslaughter but denies a charge of murder.
Opening the case for the prosecution, barrister Wyn Lloyd Jones told the jury that the couple had been together for 3 decades - and that a history of domestic abuse had outlasted their relationship.
In 2009 Barbara Yates had decided to leave the marital home - when, he claimed to the jury - the verbal and physical abuse Mrs Yates allegedly suffered intensified.
On the 18th of July last year Mr Yates drove up to the police traffic centre in St Asaph - and handed himself in, saying :'I have killed my wife. I just had enough. I have mental health issues. She's in the back of the car'.
The case is expected to last around a week.
