X Factor host Dermot O'Leary has said this will be Gary Barlow's last season judging the talent show.

Speaking at the world premiere of One Direction: This Is Us on Tuesday he said, "If Simon comes back, the dynamic would be very different. Gary wouldn't be there – he'll be leaving at the end of this year." 

He continued, "Simon is a great judge so we'd welcome him back, but Gary's been such a great head judge as well."

O'Leary also expressed an interest in taking up a seat on the judging panel himself, "I'd love to judge. I'd be so strict – I'd be nice and strict. I'd be so hardcore. I'd say it how it is."

Barlow himself has remained quiet about his future with the show but a spokeman for X Factor said, "We are currently focussing on the forthcoming tenth series, and no decisions will be made on next year's judging panel line-up until further down the line."
