A man twice convicted of murder over a fatal pub stabbing in Glasgow has been jailed for a minimum of 15 years.
David Shepherd, 32, attacked 47-year-old James Hawthorn in the Gantry Bar, Shettleston, in October 2007.
His original life sentence, imposed in July 2008, was quashed after a judge wrongly directed the jury.
Shepherd was found guilty for a second time of murdering Mr Hawthorn following a re-trial at the High Court in Glasgow last month.
He was originally jailed for a minimum of 15 years at the end of his first trial for killing Mr Hawthorn.
The conviction for murder was quashed, however, after Shepherd's legal team successfully argued that a judge had failed to mention provocation in his charge to the jury.
During his second trial, the court heard how Shepherd armed himself with a knife in the Gantry Bar.
He then followed Mr Hawthorn into the pub toilets, brutally attacked him and left him dying.
Shepherd was caught on the pub's CCTV cameras as he left the toilet.
Sentencing him, temporary judge Mark Stewart QC told him: "You have been convicted of the brutal murder of a wholly innocent man. The motive seems to have been petty jealousy.
"You deliberately armed yourself and followed him into the toilets and within a matter of seconds took the man's life.
"In court we saw a video of you emerging from toilets untroubled by what you had just done."
Judge Stewart added: "The first time you were convicted of murder the punishment part was set at 15 years. I shall set it again at 15 years."
