I remember the wasted Blair years when he was paralysed in trench warfare with Brown. Boris has been entirely sensible making sure he has he right man in the treasury so he can push forward with his agenda
We have a cabinet system of government in this country, not a presidential. One person implementing their own agenda is how business is done in a presidential system, and therefore somewhat unconstitutional (but in the absence of a written constitution, there's not much that can be done about that).
The role of PM is not in any sense superior to that of ministers, it is that of "first among equals". The decision making process has, historically, been one of consensus and collaboration. Even Thatcher mostly listened to her ministers and, when she stopped doing that, they ousted her.
Having rid the parliamentary conservative party of its moderates, and got a massive majority, any opposition that could temper Cummings' and Johnson's more extreme and bonkers notions has gone. The PCP is full of yes-men and -women, and fellow headbangers.
They have little or no regard for the electorate that voted for them, look at the way they gained all those seats in the north, then pulled the plug on the northern section of HS2.
The big mystery for me is Johnson's apparent transformation from being a socially liberal, one-nation Tory who appeared to be pretty pro-European up until that bloody referendum was called to, frankly, being a bit of a nutjob. Is he going along with all this because it suits his overweening ambition, was he a closet headbanger all along, or is he being manipulated by those who manouvered him into the position he always longed for?
Only time and history will tell, and I fear it won't be a pretty tale.
