Dermot O'Leary has left The X Factor.
O'Leary, who's hosted the show since 2007, issued a statement on Twitter on Friday afternoon.
It is unclear whether he quit or was pushed.
It had been widely suspected that The X Factor would have to make some changes to its format, panel or presenters before the show returns in the autumn, with many complaining that the last series was unsurprising and underwhelming.
The ratings for last year's final were the lowest for a decade, reported BBC News in December, even though earlier that series the show introduced changes such as Friday episodes and the return of Simon Cowell as a judge. Dermot has also been very visible on the BBC recently, taking part in a 24 hour danceathon for Comic Relief earlier this month.
