Britain's biggest entertainment show returns with another excitement-filled Saturday night, as Dermot O'Leary introduces the singing competition's remaining acts.

Nicole's boys, Tulisa's girls, Louis's groups and Gary's over-28s will be doing everything they can to stand out from the crowd, hoping to prove to the judging panel - and the nation - that they have the talent and charisma to reach the live final in Manchester this December
