I guess some of this is specifics, of course. What I'm drawn to are the ethical choices and the lack of prudence by the Prime Minister and the Prime Minister's office with regard to a trip. I guess the concern is that he exposed himself to ethical violations and, as you found, exposed himself to being influenced and using the extraordinary power of a Prime Minister to exert that influence.
As I pull away from this and we look to the future as to how to improve all this, we can do what we can, but if the code is to ask for forgiveness and not permission, it will be a challenge for any watchdog to keep people on the ethical line.
