A doorman at Stringfellows nightclub is facing jail after being convicted of killing a stag-night reveller who touched a lapdancer.
Marcus Marriott was found guilty of the manslaughter of George MacDonald, aged 34, whose head smashed onto the pavement outside the club as he was punched.
Marriott (33), of Chingford, east London, had been accused of losing his temper after being challenged by the 21-stone Mr MacDonald as he was thrown out of the central London club.
The former amateur boxer was cleared of murder in June last year, but faced a second Old Bailey trial when the jury could not agree on a manslaughter charge.
Judge Christopher Moss sent his condolences to Mr MacDonald's widow Tanya, who is understood to be considering civil action against the club.
He told Marriott that it was likely he would be going to prison but remanded him on conditional bail to January 30 for pre-sentence reports.
Marketing director MacDonald, of Southam, Warwickshire, died of head injuries following the attack in October, 2004.
Dorian Lovell-Pank QC, prosecuting, said Mr MacDonald had been swearing at Marriott as he and two other doorman escorted him out.
"In the next 30 seconds Marcus Marriott had punched Mr MacDonald so hard in the right side of his face that it
shattered his upper jawbone and sent his body crashing to the pavement where he fractured his skull," said Mr Lovell-Pank.
He said dancers at the club perform striptease, pole and lapdancing and even provide private shows.
Mr Lovell-Pank added: "But one strict rule must be adhered to - you must not touch the girls in any way. If you do, you are likely to be ejected."
Mr MacDonald, who was over 6ft tall, had been chatting with a Polish dancer named Anna.
But as Anna danced for him, "he pulled her towards him or touched her in some way".
Marriott, who had been working at the club for two years, said he had acted instinctively in self-defence when he thought he would be attacked.
Outside court, Detective Sergeant Rex Jones said: "George MacDonald was well liked and respected by his friends and those who knew him.
"He had a bright future ahead of him."
