The 30-minute weeknight entertainment show will air at 10pm for five nights of the week, shifting ITV News at Ten to the later slot of 10.30pm in a move to draw a late night audience. 

The Nightly Show will incorporate aspects of the popular American talk show format mixed with British comedy panel shows and include a topical monologue, celebrity guests and studio games.

The show will have a variety of celebrity hosts for each week, with comedian and presenter David Walliams confirmed as the guest host for the first week of the series.

Walliams said, "I am thrilled to be the first host for this brand new show for ITV."

The following hosts have yet to be announced but will likely feature a string of famous names.

The multi-million pound venture will run for 40 episodes on an eight-week trial, with hopes to make the show a permanent fixture for the channel.

Peter Davey, ITV's head of comedy entertainment, said: "We're really excited about launching this bold new show, and delighted that David will kick off what will be an eight-week entertainment treat for viewers."

Each show will be recorded live at 6pm in a central London location for the later broadcast slot at 10pm.
