X Factor champions Rak-Su debut at Number 2 with their winner's single Dimelo

This year's series champions make a strong start with their winner's single Dimelo.

X Factor champions Rak-Su have made their Official Singles Chart debut with their winner's single Dimelo. 

The track lands at Number 2 on the chart following its release late last Sunday (Dec 3). Dimelo, which was written by the group, features Wyclef Jean and Naughty Boy, who performed with Rak-Su in the live final.

The chart position is one better than the last year’s winner Matt Terry, who peaked at 3 with When Christmas Comes Around. X Factor's 2015 winner Louisa Johnson is the only other contestant not to reach Number 1 with her winner's single - Forever Young peaked at Number 9

Dimelo now a contender for the 2017 Official Christmas Number 1, which this year is revealed on Friday, December 22. Seven of the X Factor's previous 13 winners have secured it –  Ben Haenow's Something I Need was the most recent, back in 2014.
