Over the last two years, I have been able to comb through The Prince's archives. I have been free to read his journals, diaries and many thousands of the letters.

I had no expectation that the Prince would offer me the unprecedented and unfettered access to the original and entirely untapped sources on which this biography is based.

The challenge is the culture. You have to have a vision for the BBC-it can't merely be that it's big and has a place in the market.

Not every programme dealing with issues of global significance has to be fronted by last weeks winner of Have I Got News For You-but I suppose you might be wrong.

I adore Madonna. She reinvents herself like no one else.

I deplore the loss of arts on BBC One and Two.

You have to be damn certain you're putting something better in its place.
