Only ones I can think of to be honest are Nadia Almada and Brian Dowling, if we discount celeb shows. But a British teenager won X-Factor in Australia in 2011 and I think a British guy won The Voice in Germany, plus a guy who auditioned for our X-Factor but got rejected at bootcamp won Belgium's X-Factor. Although perhaps they have a backlash like this over being British rather than Dutch, Australian or Belgian.
