Trama
There are only three acts remaining in this week's grand final. After auditions, boot camp, the mentors' houses and nine live shows, the three acts remaining in the competition sing for one last time for the audience vote. The act with the highest number of votes will be crowned The X Factor champion of 2008 winning a £1m recording contract with Simon Cowell. Dannii Minogue is the only judge with no acts left in the competition.
