Tonight’s final round of auditions is followed by a heated debate between judges Simon Cowell, Amanda Holden, Alesha Dixon and David Walliams about who goes through to live semi-finals, which start on Monday, May 25.

Already guaranteed their spot in the live semis are the Gold Buzzer acts from the auditions and they are: Ant and Dec’s choice, the dance group Boyband; Simon’s singer, Calum Scott; Alesha’s street dance group, Entity Allstars; Amanda’s gospel choir Revelation Avenue; and David’s singer, Lorraine Bowen.

But there are still 200 acts hoping to claim one of the 40 places in the semi-finals.

Among them are a talking dog, a mini ninja, a dare-devil, brother-sister roller-skating act, and a hula hoop dancer that had the judges whooping in her audition.
