In the third episode of the brand new series of Britain's Got Talent, the show's four formidable judges – Simon Cowell, Amanda Holden, Alesha Dixon and David Walliams – take their seat on the judging panel in the search for the most exciting talent around.

They will be joined by the nation's favourite TV duo Ant and Dec – along with their OBEs - who will be on hand to congratulate and commiserate the acts whilst guiding the audiences through the auditions.
