We're halfway through judges houses' on The X Factor, with the final six acts for the live finals to be chosen tonight by Simon Cowell and his guest judge Cheryl and Louis Walsh who is helped by Mika.

However, host Dermot O'Leary confirmed last night that there is lifeline for some of the acts who have been sent home with the return of the wildcard selection. 

O'Leary revealed that we will learn the "details of this year's Wildcard vote" at the end of Sunday night's Judges Houses' episode.

It is most likely that four wildcard acts will be chosen – one in each category – to go through to the live shows, with the public voting for their favourite.
