Surely one ceiling looks very much like another!
Personally I would say it doesn't matter how good a leader he was-if he didn't follow the rules of behaviour (in this case shagging a married woman) he needed to go. I remember it well-a number of people whom I knew who had been 'dealt with" were ready with letters to send to the PM in the event that he had not been 1021'd. Only question I would have is who would write it?
