Businessman jailed for 14 years after he stabbed his wife to death because she mocked the size of his manhood.

A businessman who stabbed his wife to death after she mocked the size of his manhood has been jailed for 14 years.

John Clinton's 24-year relationship with Paula, 48, broke down with her taunting him about his small manhood and wetting the bed after drinking, a court heard.

In a 'horrific' attack he stabbed more than 10 times in the eye, back and chest before she fled into the street, collapsed and died. He then slashed his own throat and wrists in an suicide attempt.

A court cleared him of murder and accepted his guilty plea to manslaughter on the grounds of diminished responsibility after hearing he was suffering from a depressive illness.

'During the attack you prodded her in the breast and upper abdomen with a knife blade, stabbed her twice more to the eye and stabbed her eight times in the back,' he said.

'There were four penetrating stab wounds to the back, two of those penetrating into the right lung.

'This must have been an horrific ordeal for your wife and you let her die in the street outside.'

Paula had wanted to leave him after he refused to quit drinking, and was on the phone to an independent financial advisor when they began arguing.

Just weeks earlier she had told friends during a holiday that she did not want to return to her husband.

Clinton put his hands over her mouth to stifle her screams, then grabbed a knife from the kitchen and stabbed her in the face and chest.
