Judges have rejected the appeal of a former graphic designer who killed a Lancashire father-of-two with a broken bottle.
Ashley Charles attacked Phillip Sherriff, from Preston, at a Jessie J gig in London. He was jailed for life, with a minimum term of 14 years before eligibility for parole.
Charles became angry with the telephone executive, after bumping into him. He smashed a bottle and then plunged it into Mr Sherriff's throat.
The killer's defence team told the Appeal Court that he had not intended to kill, and the conviction should be manslaughter with a shorter sentence.
Three appeal court judges rejected Charles' appeal. Mr Sherriff's widow broke down in tears in the courtroom as their ruling was announced.
Charles showed no emotion as he was led away to continue his prison term.
