Leeds Crown Court heard that the relationship between the couple was an unhappy one and Shaw had asked his mother to leave him.

Shaw had also heard a telephone conversion the victim had with his daughter saying how he would take a knife from his partner and use it against her if she threatened him with a blade.

Shaw stabbed the victim when he saw “physical contact” between the man and his mother.

Describing the incident, The Recorder of Leeds, Judge Guy Kearl, QC, said: “In view of the nature of the attack and its persistence, there can be no doubt that you intended to kill him.”

The court heard the victim had suffered nerve damage to his face and arm.

The attack had also have a psychological effect on him.

Paul Fleming, mitigating, said Shaw had difficulty with “thinking processes” and was sorry for what he had done.

Mr Fleming aid his client believed he was trying to protect his mother despite the fact she was not harmed during the incident.

The barrister added: “This young man acted completely out of character.”

“This was an extraordinary coming together of an exceptional series of circumstances.”
