Rita Ora leaves The X Factor, leaving Simon Cowell alone

Rita Ora has confirmed that she's leaving The X Factor.

The singer, who joined the show last year, said on social media: "I had a ball on The X Factor last year and will miss the team."

Rita took on the role after being a judge on The Voice UK, which is moving from the BBC to ITV.

Rita's act Louisa Johnson won the competition last year

Her decision means Simon Cowell is the only judge left from last year's line-up.

It's after Cheryl Fernandez-Versini and Nick Grimshaw also announced they wouldn't be returning for the new series.

Back in February, Nick Grimshaw said he quit the show and wasn't fired.

"I did love it and it's not a diss to the show. It's a great show and I loved it. But it's definitely a once in a lifetime style thing," he said.

Dermot O'Leary will come back for the new series

Last year's presenting duo Olly Murs and Caroline Flack have also left the show.

They've been replaced by returning host Dermot O'Leary.

The new judging panel for this year's show hasn't been confirmed other than the announcement that Louis Walsh will be making a comeback.

Nicole Scherzinger is among the names linked with the new series

Other names rumoured to be in the running include Sharon Osbourne, Nicole Scherzinger and Mel B.
