Britain’s Got Talent ITV, 7.30pm
Ant and Dec host the first semi-final of this year’s contest. The audition process is complete, and has left judges Amanda Holden, David Walliams, Simon Cowell and Alesha Dickson with 45 acts to pick and choose from. Tonight, nine of them will be performing live in the hope of impressing both the panel and the TV audience. The winner of tonight’s viewers’ vote will automatically go through to the live grand final, before the two runners up face the judges to decide which of them will also win a place.
