"Philip Sherriff died horrifically in a way that is almost too ghastly to describe.
"The moment Charles severed his artery, Philip had no chance of surviving.
"Since that moment, Charles has shown incredible remorse, but sadly not for Philip Sherriff, only for himself.
"I hope his conviction will bring some sense of justice to the family who have been devastated by Philip's murder. He truly was a decent, hard-working family man who in no way contributed to his own demise.
– Detective Inspector Richard Beadle
"This case highlights that one single second of aggression has fatal consequences for some and a life-changing impact on so many."
He appealed to people to remember Mr Sherriff and "walk away" if tensions build up at a bar.
– Judge Paul Worsley
"This is a tragic case. Mr Sherriff may have pushed you in a crowded bar and made inoffensive remarks to a girl talking to you.
"You clearly became annoyed at what you perceived was the conduct of Mr Sherriff and lost your temper when he may have pushed against you at the bar."
Charles took a beer bottle from Mr Sherriff's hand and swung it behind him, where it broke, and then plunged it into Mr Sherriff's neck.
"It was a lethal weapon. He was a decent man," the judge added.
He said Charles had done something "which was truly out of character".
– Judge Worsley
"You did not deliberately smash the bottle you used. I am satisfied you did not intend to kill Mr Sherriff and you were immediately remorseful."
Andrew Hall QC, for Charles, said he acted "in a split second of madness".
