Axed X Factor singer Treyc Cohen's father has blasted the ITV1 show as "a fix" and "a freak show" after his daughter was dropped in favour of rival contestant Katie Waissel.
Fitzgerald Cohen, 68, accused mentor Cheryl Cole of having "sat back" and let Treyc go and called for an investigation into why the judge did not vote in Sunday's show after more than 1,000 viewers complained to Ofcom about the judge's behaviour.
Mr Cohen told The Sun: "It's a fix. It's as simple as that. I have no idea why Treyc is out. She was easily the best singer and should not have lost to Katie.
"Lots of things happen behind the scenes so certain contestants are kept in."
He added: "The show is not about singing, it's a freak show now. I think Treyc has been let down by Cheryl. She knew Treyc was the better singer, but sat back and let her go.
"She knew she was already one down after Simon (Cowell) voted for Katie, but refused to balance the score. There should be an investigation into why Cheryl was allowed to refuse to vote."
Meanwhile, Treyc admitted she was perplexed by the result and indicated that she thought the result was not fair.
"I know I finished my song and put my all into it, so if it was based on that then, yeah, I definitely feel I should have gone through," she said.
According to The Sun, figures revealed that if Cole had voted for TreyC, rival Katie would have been eliminated if the outcome had hinged on the public vote, as she polled just a third of the public votes that Treyc won.
But Katie survived her third sing-off on Sunday night after the judge told host Dermot O'Leary she was not voting, saying "I don't have to send anybody home."
