Ant and Dec host the 14th series of nationwide talent search, which sees a wide variety of acts, from comedians to contortionists, singers to spoon players, compete for the chance to win £250,000 and a coveted slot at the Royal Variety Performance. Simon Cowell, Amanda Holden, Alesha Dixon and David Walliams are once again on hand to judge this week's applicants, and each of them has the chance to put their favourite contestant straight through to the live semi-finals by awarding them the Golden Buzzer.
