ITV bosses are in hot water after an audience member at Saturday’s live X Factor final was “humiliated” on stage by a comedian who labelled him a “pikey” and “chav.”

Labour MP Stella Creasy was among members of the sellout Wembley Arena crowd who complained about the show’s abusive warm-up act Ian Royce.

She wrote on Twitter yesterday that the “comedian pulled a man out of audience and encouraged the crowd to laugh at him because ‘he was a pikey’.”

The Walthamstow MP was at the first night of the X Factor final, which was decided by a public poll last night, to support superstar constituent Fleur East.

Ms Creasy posed for photos with Ms East, who took on Ben Haenow in the final, and her grandfather at the epic event.

Ms East revealed last month that she was left in tears as a schoolgirl as a result of racist playground bullying.

But Ms Creasy revealed how Mr Royce, a comedian hired to warm up the audience at Wembley Arena during ad breaks, spoiled the big night with offensive gags.

“Suddenly not a great night when the warm-up act during adverts starts making jokes about pikeys and chavs #poorshowITV,” she tweeted.

Ms Creasy was at Wembley Arena with fellow X Factor fanatic and Labour parliamentary candidate for Ilford North Wes Streeting.

Mr Streeting explained yesterday how there were “lots of gasps” around the hall as Mr Royce dragged an unidentified audience member on stage and subjected him to degrading gags in front of the 12,000 capacity crowd.

He told the Star: “We were quite appalled by the joke, humiliating someone like that on stage is not really acceptable.

“Words like pikey and chav have just become far too accepted when you think about what they mean.”

And the Parliament hopeful added: “The point is that X Factor is a family show watched by millions of people.

“We wouldn’t tolerate other forms of prejudiced language and I don’t see why we should see those terms as acceptable.

“I very much doubt the show would accept that sort of language on air and I don’t see why it should be acceptable in front of thousands of people at Wembley stadium.”

ITV and X Factor bosses were not available for comment yesterday.

Mr Royce used Twitter to defend his offensive act, slamming complaints as “political correctness gone mad.”

The comedian, who described himself as “unscripted in life and in comedy” on his profile, later apologised to Ms Creasy.

But Mr Royce, who also works on ITV’s Britain’s Got Talent, appeared to backtrack in a longer message posted yesterday.

He wrote: “I’ll apologise when I’m wrong — always — but I won’t stand by and not defend myself when some(one) chooses to swipe someone at the very bottom of the call sheet list.”

His comments were not heard by 8.4 million viewers watching at home, which was the lowest number of viewers for an X Factor final since 2004.
