Lord Andrew Lloyd Webber has slammed 'The Voice' contestants for being unable to sing.

The musical writer - who has previously been a judge on TV shows including 'I'd Do Anything' and 'Any Dream Will Do' - believes many of the stars on the BBC talent contest struggled with their pitch, causing him to be unable to watch.

He said: "I don't know what the problem was there. Everyone was out of tune all the time. I just couldn't watch.

"Unfortunately I have perfect pitch - it's either one of the great advantages in life or the greatest affliction. When people sing out of tune, I just can't listen."

However it is not the only show he has singled out for criticism; he also believes the 'Eurovision Song Contest', in which he previously entered alongside Jade Ewen in Moscow in 2009, is racist.

He added to the Radio Times magazine: "I don't think there's any point beating around the bush. You might have noticed one thing [this year] - I don't think there was one black face on the programme.

"At the press conference in Moscow, I was asked, 'Why have you brought a black artist?' I said, 'Because she is the most talented artist that we had and I think she's a major, major star.' I think we would have come second but there's a problem when you go further east.

"If you're talking about Western Europe - Germany, fine; France, fine; Spain, fine; Greece, fine; Scandinavian countries, fine. But Ukraine? Not so good."
