Paddyann, I think the surgeon's situation is entirely different from GO's 6 jobs. As I understand what you say, she has to keep her qualifications up to date in order to be able to practise. Should she not be elected again/she decides to return to her career at some stage, that is essential. I think GO is just greedy and pushing the boundaries of greed and power to new levels.
It is particularly galling on many levels as you say isn't it? I know some MPs who are lawyers still take some cases on, but to hold 5 positions plus the MP role is greed when he's already a millionaire. He should resign his seat at Tatton, although he's not going to have it much longer anyway.
As editor of the ES he'll be championing London; so much for his commitment to the northern powerhouse. Remember when referring to that he said that he would remain as an MP to “fight for the things I care about”.
