The UK's favourite singing competition continues into its third weekend of live shows as the remaining contestants sing their hearts out in front of a live studio audience, judges Louis, Sharon, Nicole and Simon, and millions of viewers at home. This year, the stakes are even higher as the most popular act over the weekend wins a money-cannot-buy prize. As ever, Dermot O'Leary leads the proceedings and keeps the judges in check, while introducing more exclusive performances from big name guests.
