Members of the public will be banned from taking photographs of former Prime Minister Tony Blair during a book signing due to take place next month.

A strict edict laid down by Waterstone?s bookshop in Piccadilly states: ?There will be no customer photography. All mobile phones will be required to be left at the bag-drop.?

Customers hoping to meet Blair at the signing of his book, called A Journey, will be asked to check all bags into a ?holding point?, according to terms that appear on the Waterstone?s website.
