LETTER:Financial disclosure of MPs' 'consultancies'

But this only serves to obscure activities at the other end of this spectrum of culpability, where MPs exploit their privileged position to line their own pockets by selling their influence for cash. This includes not just the one-off cash payments for various services, such as putting down questions; but, more significantly, it includes the activities of PR firms, including some set up by backbench Conservative MPs, which have mushroomed over the past 15 years and now, more than any other factor, are progressively damaging Parliament's reputation and destroying its moral authority.
