Azad Singh: The killer husband who ripped his family apart

But less than six months later he murdered his wife, Kulwinder Kaur, in a rage after catching her with another man in their flat at the Pinnacle, in Gomer Street, Willenhall.

He stabbed her once in her neck, once on her shoulder and once in her side with the kitchen knife sinking up to 15cm (5.9in) deep.

Singh sought to convince a jury the first blow was inflicted without his knowledge and that he was subsequently "trying to stab her in the arm."

But today he is starting a life sentence and will serve a minimum of 14 years having been convicted of murder by a jury at Wolverhampton Crown Court.

In the trial Majinder Virk, 41, told the jury he had begun giving Mrs Kaur lifts to the Slick Stitch embroidery factory in Old Heath Road, where they both worked, in around July last year.

At first he said they did not talk during the journey but by January they were in a sexual relationship.

On the morning of January 18 they had sex in Mrs Kaur's flat when shortly after Singh arrived.

Mrs Kaur, 40, told Mr Virk to hide in her son's bedroom but 46-year-old Singh discovered him after becoming suspicious.

Miss Rachel Brand, prosecuting, said: "Singh punched Mr Virk repeatedly, took one of his phones from his hand and hit him with it.

"Singh dragged him from the bedroom towards the front door and again hit him to his face. He continued to punch and kick him."

Mr Virk escaped through the front door with aid of Mrs Kaur and Singh later pleaded guilty to a charge of assault occasioning Grievous Bodily Harm.

Singh turned his attention to Mrs Kaur, taking a kitchen knife and stabbing her three times, with the blade slicing her carotid artery.

Within minutes Singh had left the tenth floor flat and went to see a family friend to who he confessed he had killed his wife.

He was subsequently arrested and in interview said he had not realised she was dead when he fled the scene.

In the trial he said he "couldn't exactly say" how the first wound, in his wife's side, was inflicted but that he had the knife in his hand and she moved towards him.

He added: "I turned the knife to the other side and I was trying to stab her in the arm. I didn't know at that time if I had stabbed in the arm or in the neck.

"I was trying to stab her in the arm but she bent down and to the left."

He further claimed he had been taunted by his wife in the moments before he stabbed her, stating she told him their youngest son was not his.

The defence sought to argue this resulted in a 'loss of control' which reduced his actions to manslaughter rather than murder.

But the jury did not agree and convicted Singh of the more serious charge, for which he will now serve at least 14 years behind bars.
