I see today that The Speaker lost his temper with a NoLab MP Kate Hoey because she was questioning his authority. There is no question that this particular Speaker has been a shoddy individual. He has, during his time, continually exploited the rotten parliamentary system and he more than anyone has created it. When Elizabeth Filkin was the guardian of probity in the House of Commons it was Michael Martin (The Speaker) who got rid of her.
After she left then the expenses system exploded! Nobody seems to have even attempted to control it. All the people appointed by the Speaker have allowed almost every claim no matter how ridiculous. It has been a free for all which of course they are now all backtracking from. Michael Martin has been a disaster as a Speaker and should be removed and then investigated.
I understand that moves have already been made!
