A MAN fatally stabbed his cousin after an argument over a lawnmower, a court has heard.

Aaron McGuire, 28, fought with 39-year-old Kevin Gallacher in Wishaw, North Lanarkshire, on July 4.

McGuire shouted “I’m doing you” and the pair confronted one another and threw punches at each other.

McGuire fell to his knees and as Mr Gallacher walked away, he was fatally struck at the back of the left thigh.

The dad-of-one shouted “He’s just stabbed me.”

McGuire pleaded guilty yesterday at the High Court in Glasgow, to Mr Gallacher's culpable homocide.

Judge Lord Beckett QC deferred sentence until next month.
