If he's disillusioned with C4, does this mean he has quit them completely?!?!?!?!

Dermot O'Leary has signed a deal to move to the BBC in order to host a new National Lottery game show.

The presenter will host 1 vs 100, a quiz show setting one individual against 100 other contestants competing against them.

Although the 33-year-old has worked on Big Brother for five years, he has reportedly become disillusioned with the lack of new opportunities offered to him at Channel 4.

A source told the Mirror: "It's fair to say Dermot has been eclipsed on Big Brother by the fever surrounding Russell Brand, who presents the other spin-off show Big Mouth. He wants to spread his wings so he's really excited to be doing the Lottery. It's a fresh challenge."
