I’m trying to think how this would help the PLP from a tactical point of view, and I keep drawing a blank.
If I were a Labour Party member sympathetic to the PLP, I would be looking at the situation re Brexit and the increasing authoritarianism, and I would be wondering why the PLP have deemed Corbyn a bigger problem than the government. It’s just bad politics. They botched the leadership challenge, they’ve botched being a constant pain in the arse, and every time they take a swipe at him it only seems to strengthen his position with the grassroots of the party. Additionally, it all makes them look incredibly incompetent and unfit for office - I’d say they’re probably less appealing to a heartland Tory than Corbyn at this point.
The smart thing to do would’ve been to pretend to make nice and work together to stomp out the Tories on Brexit and generally raise hell in Parliament and at PMQs, while readying a coup attempt once the dust has settled. Idiots.
