I wonder if it may be more complex. One of the political problems TM faces, thanks to the combination of Miller and TM’s ludicrous electoral strategy, is reliance on the DUP. Has this influenced the deal on the table (in that EU negotiators will have been very aware of this)?
I’m not convinced the EU have ever taken the deal on the table seriously; they’ve always known Parliamentary approval meant it was a dead duck. If Parliamentary approval hadn’t been needed, how would that have influenced the EU’s (and UK’s) game plan and tactics? This is unknowable but I suspect we might well be looking at a very different deal.
The Miller strategy was a high risk one in the context of the referendum: the most likely results of requiring a Parliamentary approval have always been either no Brexit, or a very bad one.
Either way, the result is some nasty consequences for ordinary people in terms of social harmony, political disruption, risk of rise of extremist parties, loss of respect for democratic institutions, and economic disruption. But the Miller strategy offered at least a chance of the financial services industry protecting themselves (no Brexit).
I think her actions damaged our country, while protecting the financial services industry. Not a fan. I doubt very much she ever had in mind anything other than the profits of the London based financial services sector, and I don’t like that sector anyway. Would not have mourned it.
