Like my right hon. Friend Mr Francois, I served for four years in the coalition Whips Office, including for two years with Mr Carmichael, and he and I will remember all kinds of cock-ups, for want of a better term: people inadvertently paired twice, people who thought their pair was transferable, and so on. All these things can and do happen. In my view, this is much more likely to have been a genuine mistake, so does my right hon. Friend agree that it would be a poor decision to base long-term practice on this one case, however high-profile?
