I think it needed another episode, essentially we are asked to create our own episode. Ok so he gets no 10 but his wine has not signed to dissolve the dodgy CO, so I suppose we are meant to think that he'll be forced to resign pretty quickly.
It did leave quite a lot in the air. The shift of power towards the wife, though holding an incriminating document can only be a threat for so long. His relationship with his new-found daughter.
Although it was a fun romp I hope there isn't a second series as there were too man inaccuracies and anomalies.
