It's X Factor final night tonight, which may not be as much of a national event as it used to be, but no doubt it will still pull in the viewers. Before the winner is announced, 5 After Midnight, Matt Terry and Saara Aalto face yet another showdown, as judges Simon Cowell, Louis Walsh, Nicole Scherzinger and Sharon Osbourne deliver their verdict on each act's performance one final time. Taking to the stage alongside a surprise guest performer, the acts sing two songs each in front of an audience of thousands at Wembley Arena. The act with the lowest public vote figures will face an early exit from the contest this evening, bowing out in third place, while the overall winner will be announced tomorrow evening.
