I like to know why a video has suddenly gone viral, why a song has broken, why a TV show is suddenly rating out of pattern... I'm pretty good at understanding why things are becoming popular.

I have seen that the American Dream is a reality - and I would love to feel the British Dream is also a reality. To enable that, we have to bring back some common sense and encourage family values, a proper sense of justice and make people believe they have a decent chance to build a business or career for themselves. I see this moment as a fantastic opportunity to restore this, because I believe Britain Has Talent.

I think that by ignoring the show you're ignoring the audience who put you there.

I thought the first two seasons of America's Got Talent were good. I think this one is the best one by a mile because they - you see the difference this year, I think, with the crowd being effectively the fourth judge. But most importantly, I think that these shows have to have a relevance because if you're not finding stars at the back of these shows - whether it's Idol or Got Talent - they're a complete waste of time.

Whether they run a record company or a grocery store, every boss will tell you you're in big trouble if you're borrowing more than you can ever afford to pay back. Delaying the pain for future generations is suicidal. We've got to start getting the deficit down right now, not next year.

I have very good advice to give to kids this age, which is, you shouldn't listen to your mum or dad and you just have to work it out for yourself. And the reason I've taken the age range down this year, and I never would have done it 10 years ago, is what I've seen with the success of Willow Smith. You don't have to be so cutesy anymore.

I have always hated celebrities lecturing people on politics.
