Matt Cardle's manager has revealed his frustration at the X Factor's apparent "blacklisting" of the singer.

The vocal talent won the TV talent show back in 2010 and he has enjoyed a relatively successful career upon leaving the show, which has included a No.1 single.

A recent video issued by the show to promote the upcoming series of the X Factor, however, has angered Cardle's manager Will Talbot after it declined to feature the singer alongside other previous contestants.

Speaking to Digital Spy, Talbot believes the X Factor is trying to "erase" Cardle from their history books. He said:

"It is very disappointing to see Syco, yet again, attempting to erase Matt from the history books. 19 million people tuned in to watch him win (on their most successful series ever). Since then, he has been bizarrely blacklisted from appearing on The Xtra Factor, excluded from every video compilation celebrating the show and he now won't be featured in the X Factor 10th anniversary video which airs tonight.

"Since 2010, he has had two top ten albums, one of which went platinum, and his combined single and album sales exceed 2 million units. In light of this, for them to purposely keep excluding one of their winners is undeniably perplexing to say the least. In truth, it pretty much sums up Syco's attitude to him during the months after he inconveniently (for them) won the show. Unfortunately there is a misconception that Matt has slagged off the show and fallen out with Sony but this is not true."

The music manager continued: "He once jokingly said in an interview that he 'compromised his integrity on The X Factor by wearing yellow trousers whilst singing Katy Perry songs'. Well, did you see those trousers?! Matt has repeatedly said how grateful he is to Simon [Cowell] and the show for the opportunity and how much he enjoyed being a part of The X Factor. He still feels that way. This reflects very badly on Syco."
