A 42-year-old man has been jailed for life after he stabbed a young father in the neck in an unprovoked attack.

Colin Welsh was told he would serve a minimum of 12 years during the sentencing at the Old Bailey yesterday.

The brutal assault took place at a house party in Kentish Town in 2008.

The court heard how 27-year-old Elliot Guy, who had a 12-week-old daughter, was in the toilet when Welsh stormed in and stabbed him in the jugular.

Mr Guy staggered out of the party and was rushed to the Whittington Hospital but his heart had already stopped by the time he got there and he died after about an hour.

At the sentencing, it emerged that Welsh - a paranoid schizophrenic - has a string of previous convictions including violent crime.

Judge Brian Barker told Welsh: "You took a knife with you to a social occasion. This act was a horrific and totally unprovoked killing."

Welsh had previously admitted manslaughter by diminished responsibility.
