The fifth series will see more singing hopefuls audition in the hope of securing a recording contract with Universal Music and launching a music career, but what's happened to past winners of the show?
2012: Series 1: Leanne Mitchell
Mentor: Tom Jones
Leanne won the first ever series of the talent show, and was often praised each week for being consistent in her delivery of songs and for showcasing her powerhouse vocals. Her debut single 'Run To You' peaked at number 45 in the charts, and her self-titled debut album, released in May 2013, reached number 134. Leanne was dropped from the label in 2014. A year after winning, she slammed critics and said she was fed up of being used as a "scapegoat". She wrote: "For the record, I'd written and finished the majority of my album by the end of last summer, around September time... I don't know why it was decided to wait so long to release it, but unfortunately, being very new to all this and probably too naive, I had to trust the people around me in making the right decisions." In December 2014 she revealed that she became a first-time mum to baby son Leo.
2013: Series 2: Andrea Begley
Mentor: Danny O'Donoghue
Andrea, from Northern Ireland, was triumphant in the second series of the talent show after beating Leah McFall. Her winning single 'My Immortal', which is a cover of the Evanescence hit, peaked at number 30 in the charts. Her second single, 'Ho Hey', charted at number 98. However, Andrea had more success with her debut album The Message, which came in at number 7 on the album charts. In an interview with Belfast Live in July 2015 about her new role as ambassador for sight loss charity RNIB NI Andrea said: "I am just gigging and singing away and hoping to knock Taylor Swift off the number one spot one day. I am just enjoying it and doing as much as I can and hopefully do more touring. It is great to do the RNIB stuff in a different capacity." She also revealed plans to release an album inspired by folk music, adding: "I think it reflects a bit more on me."
2014: Series 3: Jermain Jackman
Youth politician Jermain won the third series of the show and received messages of congratulations from X Factor judges Simon Cowell and Cheryl Fernandez-Versini and Labour leader at the time Ed Miliband. Jermain's cover of 'And I Am Telling You I'm Not Going' finished at number 75 in the charts. His self-titled debut album, released in April 2015, missed out on a Top 40 position, charting at number 42. Jermain revealed to the Daily Mirror in November 2015 that he was taking a "step back" from music. "I've stepped back from music for now," he said. "I saw some things I didn't like and I was losing the love for music. Maybe I'll come back when I'm 23 and I've got my degree in politics." Jermain also said he was no longer in contact with Black Eyed Peas star will.
2015: Series 4: Stevie McCrorie
Mentor: Ricky Wilson
Former fireman Stevie was the fourth winner of the talent show beating Irish opera singer Lucy O'Byrne to the coveted spot. The Scottish singer released his winner's single, a cover of Adam Levine's 'Lost Stars', which peaked at number 6 in the charts. His debut album, Big World, is due out this month. In November 2015, Stevie said he was keeping his old job as a fireman open. He told The Sun: "I'm still employed by the Fire Service but on a break. I don't want to just leave because it's a great job and it made me who I am."
