A cabinet minister who keeps his mistress in satin sheets at the French taxpayer's expense cannot justly object when the press exposes his misuse of public funds. Our freedom to scrutinise the conduct of public figures trumps that minister's claim to privacy. The question is: where and how do we draw the line between a genuine public interest and that which is merely what interests the public?
