Irish music mogul Louis Walsh is to quit his long-running role as a judge on British TV talent show The X Factor after 10 years. Walsh is the last remaining original mentor on the panel, following Simon Cowell's move to head up the U.S. version of the show, but he has announced the next series will be his last. He tells TV Times magazine, "I'm happy this is going to be my last year. I've been judging X Factor for 10 years so I've done it all." Walsh was on the original panel of judges when the hit singing contest launched in 2004, alongside Cowell and Sharon Osbourne, who has recently agreed to return to the show after quitting in 2007. A spokesman for The X Factor says, "We're delighted Louis is back for a record breaking 10th series this year. It's far too early to say what the judging panel for 2014 may or may not look like." Before signing up to The X Factor, Walsh previously worked as a judge on another U.K. reality TV series, Popstars: The Rivals - the singing show which discovered British pop group Girls Aloud.
