Jermain won the BBC singing competition in 2014 after being mentored by Black Eyed Peas star will.i.am.
Speaking to the Daily Mirror, Jermain said: "I've stepped back from music for now. 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 revealed that he is no longer in contact with his former mentor will - but he said he isn't surprised by it.
"I haven't spoken to will.i.am in a while, which I'm not shocked by," Jermain continued. "It's a TV programme, nothing more, nothing less."
Jermain stormed to victory as winner of the third series of The Voice UK when he was just 19 years old. He was sent messages of congratulations from X Factor boss Simon Cowell, Labour leader at the time Ed Miliband and Cheryl Fernandez-Versini.
Winning the show meant the London-born youth politician secured a record deal with Universal Music. However, he failed to make his mark on the music industry following the release of his self-titled debut album.
