One thing I have always said about Ken is that I am 110% sure that he would not have been enriching himself at any time by any improper actions in any role he has had. He is simply a political bore who does it for the political power alone (something which is in it's own way a bit scary - I'm not sure his dignity is surviving his David Brent act since being deposed!).It speaks volumes of Ken's integrity that despite the best efforts of a massive, well-oiled, multi-billion media machine charged with digging up any dirt they could find on him, they were barely able to muster up a single thing that stuck during his long years in office.
I can't say the same for many of his cronies but I would be extremely surprised if it ever turned out Ken was guilty of anything other than naivety in his dealings with them.
