Rak-Su win The X Factor 2017

The four-piece boyband had performed two of their original songs during Sunday night's live grand final- Touché and Mona Lisa - and managed to beat fellow singer-songwriter Grace Davies to The X Factor crown.

After winning, Rak-Su were elated with band member Jamaal telling Dermot O'Leary: "I just want to thank everybody at home, everybody here, all my family who have made this experience so special. I'm speechless, honestly."

Meanwhile their mentor Simon Cowell first of all thanked Grace before saying that the boys were "gentlemen" and "stars" and gave a shout out to everyone who voted.
