The first of this weekend’s bootcamp double bill, as the cream of the crop from the nationwide auditions head to London. Over 200 acts will be tested to the limit at Wembley Arena in the biggest bootcamp ever. They will face choreography, vocal coach... (more)ing and styling sessions as they try to stand out from the crowd. Those that make it through the first challenges will get to perform centre stage in front of Simon Cowell, Louis Walsh and guest judge and Pussycat Doll Nicole Scherzinger. Host Dermot O’Leary will be there at every step of the way as we find out who makes it through and who heads home.
