Peter Moore, 28, of O'Hare, was found guilty of murdering his brother Derek, 25, at a flat in Drive Road, Govan, on January 3.

He now faces life imprisonment and next month judge Lady Wolffe will determine how long he must serve behind bars before being eligible for parole.

She said: “You have been convicted of one of the most serious crimes that can be committed in this country. You will be looking at a substantial custodial sentence.” The fatal stab wound which caused massive internal bleeding was to Mr Moore's abdomen.

He was stabbed four times and had in total 75 injuries to his body.

The High Court in Glasgow heard that the two brothers had been staying at their mother's Glasgow home over the festive period.

In a police interview Moore told detectives: “I said I wasn't going to fight with him again.” The court heard that on a previous occasion Derek Moore broke his brother's jaw.

Moore told police: “When we fight we fight for hours. I can't remember arguing with him. He's pure evil when he's been drinking. He started it and now he's dead.” Moore's partner Ashley Picken, 24, told of how she was woken up by the sound of the brothers arguing and fighting.

When asked how Derek Moore had been earlier that night she replied: “He was angry.” She told prosecutor Paul Kearney: “I looked out into the hallway and I saw Peter standing over Derek with a knife in his hand hitting Derek. He was hitting Derek in the legs and the side of his body with the knife. Derek was lying down on the floor on his back.” Moore, who has five pages of previous convictions including a number for violence, did not give evidence during the trial.
