Rak-Su win The X Factor 2017 final, release winner's single Dimelo

Can they claim this year's Official Christmas Number 1?

Rak-Su have stormed to victory in The X Factor final.

After a tense three-way battle on Saturday against Grace Davies and Kevin Davy White, Rak-Su went head-to-head against Grace Davies tonight before emerging as winners of the musical juggernaut's 14th series.

The Watford quartet now release their winner's single Dimelo, which is available to download and stream now. Rak-Su are the first X Factor victors to release a winner's song they'd written themselves. 

Mentored by Simon Cowell, the foursome – made up of schoolmates Ashley, Jamaal, Myles, and Mustafa – have been firm favourites for much of the competition, with their original material being well received by the show's fans when made available on download and streaming services.

Rak-Su were lucky enough to duet with Wyclef Jean and Naughty Boy on their performance of their winner's single on their way to lifting the X Factor trophy.
