One of the only reasons we're watching this is David Walliams, and his (albeit orchestrated) banter with Simon Cowell. The search for new talent continues as more hopefuls take their turn in the spotlight in front of the audience and judges Simon Cowell, David Walliams, Amanda Holden and Alesha Dixon. Hoping not to hear the dreaded sound of the panel's buzzers, the auditionees have one shot at winning over the judges and being in with a chance of scooping the prize of £500,000 and a slot at the Royal Variety Performance. Ant and Dec are backstage with the entertainers.
