Not to be sounding racist in any way, shape or form by any means but it's UK X Factor......now bare with me on this???
In the UK, white/British are still the majority ethnicity, Asian, European and other UK born nationalities are still believe it or not minority groups so the odds on the winner being white/British will ultimately be much higher. Actually, we've had two solo winners who were of mixed race so technically the theory on statistics doesn't hold up?
I'm fairly certain that a white/Asian born person would have less chance of winning an Asian X Factor show or a non American, the American X Factor? The results are probably the same worldwide?
I'm not a worldwide X factor fan so can't say for sure who's won where?
