In the fourth episode of the brand new series of "Britain's Got Talent," the dream team of judges - Simon Cowell, Amanda Holden, Alesha Dixon and David Walliams - once again take their places on the panel, as they continue their search of the most astonishing and exhilarating talent around.

They are joined by the nation's favourite TV duo, Ant & Dec, who will be on hand to encourage, congratulate and commiserate the acts whilst guiding the audience through the auditions.

Together they have scoured the country looking for a winning act who can entertain the nation and capture the hearts and imaginations of the Great British public.

With thousands of people applying, viewers can expect to be amazed and astounded by the remarkable line-up of acts competing to be crowned this year's winner, securing an incredible £250,000 and the opportunity to perform at the Royal Variety Performance 2016.
