A jealous husband tried to snap his wife’s neck after hacking at her with a meat cleaver, the Old Bailey heard.
William Clapperton, 58, attempted to break his estranged wife’s neck with his bare hands like something you would see in a film, the court heard.
According to prosecutors Clapperton could not stand the thought of another man being in his wife’s life.
Summing up his case, Mr Markham added: “If he could not have her then nobody else could.”
The defendant left Napangkawarin Clapperton covered in blood from wounds to her neck, jaw, and eyes on 17 February this year, prosecutors claim.
He then collapsed on their bed and began to slash at himself in a crazed fury, jurors were told.
Police discovered him bleeding and rushed him to hospital where he was treated.
Prosecutors say Clapperton wrote to his estranged wife apologising for the attack but claimed he could not recall it.
Napangkawarin managed to escape their home in Twickenham, London, and was treated at St Mary’s Hospital, Paddington.
Doctors had to wash away blood from her face and hair which was matted together before they could stitch her wounds.
Dr Ashley Fegan-Earl found the wounds to the neck were caused by slashing through skin and fat.
“His opinion, as an expert, is that she sustained, or was the victim of a sustained and dynamic assault and the attack focused on the head and neck region rather than on the torso,” David Markham, prosecuting, said.
“The wounds to the neck are a combination of slashing and chopping.
“The wounds and cuts to the neck were the most life threatening because of the vessels in the neck.
“The defendant, her husband, tried to break her neck with his bare hands like something you see out of a film.
“It will be the defendant’s case that he did not intend to cause the injuries and did not act intentionally and there maybe an element of accident.
“The defendant was, you may think, under the influence of alcohol to one degree or another.
“He was to speak of these events after he was charged in letters addressed to his wife from whom he was separated.
“In those letters the defendant apologies for what had happened, professing little memory of what had taken place but saying he was ashamed and embarrassed.’
The court heard when police raided the flat they found him unconscious and bleeding from self-inflicted wounds on the bed.
Nearby was the black handled cleaver allegedly used in the attack and a kitchen knife,as well as blood stains on the floor and duvet.
Clapperton was arrested and formally charged on February 20.
He made no reply when questioned by officers about the events.
Clapperton of Twickenham, denies attempted murder and the lesser alternative of causing grievous bodily harm with intent.
The trial continues.
