I know where I will be next Thursday

The Bookseller informs me that:

'He (Peter Mandelson) will sign copies of the book at Hatchards in Piccadilly, central London, on 15th July.'

I wonder if he will take questions? If so what should we raise with him: dodgy mortgage applications, the Hinduja brothers, whether his prime loyalty is to the EU or the UK, whether he had sexual relations with any Labour ministers whether before during or after they served in government?
