He seems to me to be even handed in who he calls to speak and he looks after the interest of parliament, whoever is in power. He was just as criticised when Labour was in power but the Government has executive power: the speaker, as balance, protects parliament which is not the government but the back benches on all sides. I think he is one of the best we have had. He has done a lot to open up parliament and make knowledge of how it works, etc., more so available. Oh, and as he has to, he gave up his membership of the Conservative party.
