Dermot O'Leary thinks that Louis Walsh is the 'dirtiest' judge on the X Factor's panel.
The presenter has hosted the ITV singing competition since 2007 and has now revealed that Louis is the most ruthless member of the judging panel.

Speaking to The Sun newspaper, he explained: "I love it when the panel is fun and when they are a bit spikey with each other, so long as they don't resort to the proper dirty stuff like Louis does.
"If I was a contestant, Louis would be the judge I'd want because when we go to the studios he is the dirtiest judge we have."
He does however think Louis' "unorthodox" antics make him a "valuable" judge, despite his "unconventional" mentoring methods.
"He's unorthodox and unconventional but I couldn't make the show without Louis.
"I adore him.
"In many ways he's the most valuable person on the panel. I can always rely on him to give me a tiny bit of insanity.
"He laughs when everyone else cries and cries when they laugh. He walks to the beat of his own drum. He's an extraordinary man."
