Dermot O'Leary quits Big Brother

X Factor presenter Dermot O'Leary has quit Big Brother's spin-off show Big Brother’s Little Brother. But he will be presenting E4’s Big Brother: Celebrity Hijack in January.

Dermot said: “It is with great regret that my time on Big Brother will come to an end after Big Brother: Celebrity Hijack.

“For the past seven years I’ve had the time of my life working on Big Brother’s Little Brother.

“But this summer’s work commitment of BBLB and The X Factor has proven to me that to do both shows is impractical if not impossible.”

The X Factor auditions and Big Brother both take place in the summer and it must be very difficult to cover both at the same time.
