Britain's biggest TV talent competition returns to ITV this week as the search for this year's most exciting acts gets underway with brand-new BGT hopefuls joining returning performers in a season of shows which promises drama, upset and family-fun galore. Fan-favourite Ant McPartlin makes his emotional return to television tonight after committing himself to rehab early last year and joins his iconic presenting partner Declan Donnelly for the first time in over 12 months. Series regulars Amanda Holden, Simon Cowell, David Walliams and Alesha Dixon all return to the judges' panel while Stephen Mulhern reprises his role as presenter of the series' behind-the-scenes spin-off, Britain's Got More Talent. As we kick the auditions off tonight, expect the weird, the wonderful and everything in between. The judges find themselves on the receiving end of a roasting at the hands of the Queen, while some dynamic dancing and enchanting vocals sprinkle a touch of star-dust on the show. Britain's Got Talent - Saturday 7:15pm on ITV.
