I’ve just finished reading a great book by Jeremy Paxman (of all people) called The Political Animal. Quite a depressing book about the career of a politician and how they have to keep their own beliefs and principles quiet in order to make any advancement.
In it he mentions an organisation called Transparency International (http://www.transparency.org/) which monitors corruption in governments around the world.
The good news is that the British govt comes quite high (scroll down) – 11th in fact where 145th (Haiti and Bangladesh) is bottom. America is joint 17th with Belgium and Ireland so it seems the land of the free is Finland. Good news for brown bears and wolverines, then.
