It's the final audition night on BGT with members of the public having one last chance to impress the judges enough to earn a place in the semi-final. As always, Simon Cowell, Amanda Holden, Alesha Dixon and David Walliams are on hand to appraise their performances, but once this stage of the contest is completed, the judges must then move on to the much more demanding process of whittling down this year's crop of contestants for the live shows, which will take place every evening next week on TV3 at 7.30pm.
