X Factor: Theme, song choices and guest performers revealed

Last week saw a double elimination with Sam Black and Sean and Conor leaving Saturday night and Rai-Elle and Holly Tandy going home on Sunday. This leaves six contestants to fight for a place in next week's final.

Simon Cowell has two groups, Rak-Su and The CutKelvins. Sharon Osbourne with her last girl Grace Davies. Louis Walsh with his last boy Lloyd Macey and Nicole Scherzinger with two overs Kevin Davy White.

Last night we said goodbye to Matt Linnen.

The contestants will be celebrating the best of British music with the theme ‘Cool Britannia'.

All the contestants will sing one song each night. One will leave at the end of Sunday night.

Here are their song choices for Sunday's semi-final:
