The Lewisham and Greenwich choir now look unbeatable for the Christmas number one spot, due to be announced at 1pm tomorrow.They were given a late boost by rival Justin Bieber, who tweeted to his 71.9 million followers yesterday that they should support the song instead of his own release 'Love Yourself', which was running neck and neck.

With just 24 hours to go, bookies have closed the betting on the single. Coral suspended betting by 8pm last night, saying Bieber had all but guaranteed his competitors' triumph.
