I think you have to judge everything based on your personal taste. And if that means being critical, so be it. I hate political correctness. I absolutely loathe it.

My proudest achievement has been the success of the shows and artists I have been involved with, because they were made in Britain.

Every time I sat in a chemistry lesson I thought, what am I doing this for? I don't ever want to be in a job that involves a Bunsen burner.'

My dad wasn't someone who was a great disciplinarian, we had a fun relationship, but he gave me really constructive advice in my life, which I still carry today and I do pass on to other people. So if I can have the same relationship with my son as I had with my dad, then I think he'll be very happy and I'll be very happy.

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.
