Ant and Dec host the fourth audition round of the nationwide talent search, which sees a wide variety of acts, from comedians to contortionists, singers to spoon players, compete to impress judges Simon Cowell, Alesha Dixon, Amanda Holden and David Walliams. Whomever the quartet choose to send through to the live stages will then be in with a chance of winning a huge cash prize and a coveted slot at the Royal Variety Performance later this year, following in the footsteps of 2017 winner Tokio Myers.
