Douglas Carswell MP (uKIP, former Tory) wrote this in the Daily Telegraph in 2013. He appears to be sYing Bercow is not biased toward anyone, but he puts the Institution of Parliament first. It sounds plausible:
// John Bercow is not biased – and it's a myth that he's loathed on the Tory backbenches
Speaker Bercow has been upsetting some of the more sensitive souls in the House of Commons. The poor dears!
Ministers turn up in the Commons to announce a series of closures, without bringing the list. Then Mr Speaker barks at them.
MPs given the chance to grill ministers about government policy, instead make a childish points about Labour policy. Bercow ticks them off.
Hang on a second.
How dare a minister turn up to make an announcement that will impact the lives of thousands, without bothering to bring the detail? How demeaning that an MP should ever ask a toady question, intended to gain favour with the whips?
Politicians' pet pundits might sneer at the Speaker. The rest of the country should cheer him each time he ruffles feathers.
Don't misunderstand me. John Bercow's politics are not mine. And his wife's antics strike me as bizarre. But as Speaker of the House of Commons, he deserves support from all those who think Parliament ought to do better.
Thanks to Bercow, the Commons is starting to count once more.
Backbenchers can table Urgent Questions, keeping ministers on their toes. Bercow selects amendments intended to test the Government's position. He has speeded up the tempo of debate; experienced ministers are no longer able to hide behind long winded waffle.
Perhaps the most facile charge against the Speaker is that he's biased.
The whole point of having a House of Commons is that it holds the government to account. The Speaker's job is to make sure it does its job. In doing so, he is – by definition – going to uphold the authority of the Commons against those on the government benches. With Tory ministers sprawled across those government benches, that means he'll often be admonishing a Tory.
So why do we keep being told that the Speaker is partisan? Precisely because he changing the cosy Westminster way of doing things.
For too long, our legislature has been a useless facade. All the important decisions have been carved up by "the usual channels", the system that gave us the old MPs expenses regime. The backbenchers have been reduced to being little more than cheerleaders for party leaders.
Bercow is helping restore purpose to Parliament. He is lifting the legislature off its knees.
Ministers may grumble. Whips will whine – and brief the press. That should reassure the rest of us that Bercow is doing something right.
Incidentally, it is a myth that Bercow is loathed on the Tory benches. If the front bench ever put his authority to a vote, the backbenchers would support him. And the grandees know it, which is yet another reason they can't stand him. //
