Try as we might to get a definitive answer as to why Republic of Ireland viewers are unable to vote this year, we're still left a little bit in the dark. It's a shame considering Eoghan (who Charlie Brooker recently described as a clone of Jamie Oliver which has been brought up in a bag) might need all the votes he can get. Tonight, Dermot O'Leary presents big band night, traditionally a real test for the hopefuls as they sing a swing classic accompanied by a full live orchestra. Good practice for their cabaret jobs in later life. The remaining 10 acts will have to raise their game as they perform for those all-important viewers' votes while also impressing judges Cheryl Cole, Simon Cowell, Dannii Minogue and Louis Walsh, who as ever will decide the fate of the two acts with the fewest votes. The results can be seen at 10.10pm.
