Channel 4 is preparing to announce details of a new daily reality show from Big Brother producers Endemol, the Media Guardian said today.

Provisional schedules indicate that a new one-hour show will air nightly on the network in a 9pm slot from Wednesday, December 7.

The website speculates that the new series of Celebrity Big Brother could be brought forward by a month to fill the space or that it could be taken by a new Big Brother spinoff currently in development.

An announcement on the show is expected tomorrow (Wednesday).
