Heather Brooke was a guest on Radio 4's Start the Week programme today

Heather Brooke: we should all be very grateful to her. It was she who started the work of exposing the dishonest expenses claims of our MPs.

Today she was on Radio 4's Start the Week in order to talk about her new book, The Silent State, which is due out next week. In it she draws attention to the lack of transparency at all levels of government, in contrast to the increasing erosion of privacy of ordinary citizens who have to provide more and more information to the State. See Heather Brooke: The Silent State.
