Alexander Armstrong's Big Ask is a panel show designed to challenge Britain's wittiest people to work harder on television than ever before.

The host not only wants his guests to answer questions on the topics of his choosing, he needs them to make up the questions too. The show covers topics as varied as Shakespeare, magic, weddings and the Bible.

Come Dine With Me voiceover man and comedian Dave Lamb sits in his very own 'fact bunker' dishing out fun factoids and extra helpings of trivia.

Guests on the series include Jimmy Carr, Rufus Hound, Andi Osho, Robert Webb, Sandi Toksvig, Marcus Brigstocke, Clive Anderson, Sue Perkins, Daniel Sloss, Russell Kane, Mark Watson and Ed Byrne.

Our Review: The idea behind this panel-cum-quiz show is simple, but good. Alexander Armstrong throws out categories, and the guests taking part have to come up with a question they know the answer to, but one that they hope will stump their fellow players.

Some of the questions dreamt up by the guests are fairly highbrow and the host adds a touch of class too, but as guest Robert Webb pointed out in the pilot, it's airing on a digital channel that has a certain demographic: "it's not called David, it's called Dave" - so Big Ask doesn't ever quite get to QI levels of sophistication (not that that is a complaint, to be clear).

Due to the format, Armstrong doesn't really have to ask any questions, but he avoids making himself redundant by delivering some fairly good one-liners to fill the gaps and smoothly guide the conversations in the right direction.

However, sadly what could be one of the strongest elements of the show is under-used. The cheery and very likeable Dave Lamb is stuck in the show's 'bunker', where he doesn't have much to do. In the pilot he had the job of validating the answers, but as the questions are clearly pre-prepared it felt false; unfortunately it means his role has been reduced even further in the series, and he only occasionally gets to butt into the conversation now and then to share a fun fact or video clip.

Overall, this is an entertaining show and a pat on the back to the people at Dave for making it.
