Ant and Dec host the fourth audition show, as the judges - Simon Cowell, David Walliams, Amanda Holden and Alesha Dixon - give their verdicts on more of the nation's best, and worst, performers. Queuing up to take the stage, acts of all ages and abilities are determined to prove they're worthy of the £250,000 cash prize and a slot at this year's Royal Variety Performance, but while some of them will be deserving, the dream will be over for those whose auditions are cut short by the panel.
Britain's Got Talent is a reality talent show hosted by Ant and Dec. Any sort of entertainment act is able to enter the competition and hopefully impress the judges and make it through to the final stages of the competition.
The series winner's prize is £100,000 and the chance to perform at the Royal Variety Show. The judges on the show are Simon Cowell, Amanda Holden, Alesha Dixon and David Walliams.
