One Direction and Emeli Sande are set to perform at The X Factor final, it has been confirmed.

The boyband, who finished third in the 2010 series, have made several appearances on this year's show following their worldwide success.

Sande performed Beneath Your Beautiful with Labrinth a few weeks ago, and her songs have featured prominently in the competition, particularly Read All About It (Part III).

The final acts who remain on The X Factor are Union J, Jahmene Douglas, Christopher Maloney and James Arthur. They will battle it out for a place in the December 8 final this weekend.

More guest acts are expected to be announced for the final, which will be hosted by Dermot O'Leary in front of 12,000 fans at Manchester Central.
