2 more things if I may. 1.) I don't think it reflects well on the Speaker either. For our Parliamentary system to work, the neutrality of the Speaker, who acts as the "referee" must be beyond question. I think it is incredibly difficult to make a good case that Speaker Bercow is not being partisan in the way he applies his discretion (or doesn't.)
I generally think, that Bercow honestly does this.
The problem is that the executive has tried to over play its hand repeatedly over the last three years by trying to cut parliament out of the equation by trying to act unilaterally.
You can see this in May's attempt to trigger a50 without parliament.
Both her and Johnson have acted beyond the limits of their power and had the courts rule on this.
This is ultimately going to be frustrating for anyone with an authoritarian mindset, because they want to just do things rather than be forced to compromise (which is what liberalism is in essence based upon). The authoritarian mindset is precisely to control things and get things done with an authority figure who has the power to make decisions without consultation.
You can hear this in the spoke desire to 'have a strong leader' and all this stuff about the force of Johnson's personality.
The reality is that our system is a parliamentary democracy which is based on compromise.
You then throw the decision to have a GE and the loss of a majority which has only compounded authoritarian frustration in not just being able to 'get on with it'. Bercow simply become the visible manifestation of the fact this is a minority government.
Parliament's job is to come to an agreed position where there is a majority and if there isn't one, to come to a compromise in certain areas where there is disagreement through the amendment process. In this sense is merely doing his job and he was always going to be more visible in any situation where there wasn't an obvious majority over a time pressured policy which Brexit became after a50 was trigger. (again this could have been avoided if there hadn't been this self harming act of triggering a50 without knowing what the fuck we were doing).
The optic problem we see playing out in the press is merely about how cultural difference in the culture war are aligning with political parties, with authoritarians in government and a more liberal approach on the opposition benches (I note here that the opposition benches are NOT only populated by liberals there are also many authoritarians on the opposition benches).
The Tory Rebels who were thrown out of the party were the ones on the government benches who didn't have this authoritarian mindset and see value and importance in the process of parliament. Ultimately most of them look like they will vote for the deal with the government - the point being that they wanted to defend parliament. These MPs will largely be gone in any new parliament and that is a worry in itself.
I suspect the next speaker will face even greater pressures to stop the executive acting beyond its power if Johnson does win a majority as parliament will not be able to hold him to account. The only option then would be through the courts.
And of course with a majority and a party behind him with full on authoritarian mindset, can simply rip up the court system and dismantle the pillar of justice which upholds the democratic system in this country.
Thus the executive will indeed 'take back control', but that will not be for the people. That will be unchecked power that can not be held to account in which corruption will flourish and abuses of power against the people by the state can prevail.
The Human Rights Act will be toast and there will be no more protection from European Law. Even the ECHR will be weak in its ability to rule on cases in the UK.
That is where everything is going. Some of us were aware of this pre-ref. What has played out since has only served to prove the point in its various ways.
