Re. "wilfully ignoring" - Did she not say a few days ago that she, "as Prime Minister" would "never" revoke art. 50? One can interpret that as, "if the House puts up a majority to replace me and THEN instructs a successor to revoke art. 50, be my guest". I know, fat chance.
You won't suspect me of undue sympathy with IM Mai, but in all fairness to her, she did tell Parliament that the decisions now were between
no deal and out in in a week,
her deal with short extension,
long extension+EU elections+ reset/rethink, and
no Brexit,
where the last option would not be available to a PM May because she is adamant she will either deliver Brexit or be no-confidenced out of her job. I think she isn't wilfully ignoring the possibility, she is frank about the fact that she will do everything to prevent it - preparations be damned.
So no. 3 is ruled by the EU and no 4 is ruled out as long as she occupies No. 10. Thus, binary decision. Sooo, Mr. Speaker? Still bent on no deal in a week, instead of being generous with an age-old rule?
If I didn't dislike her so much, I'd call her maneuvering in order to get what she wants shrewd. Viewd from this side of the Channel, Bercow's move, otoh, comes across as a rather crude attempt to back
her into a no deal/no Brexit corner. And he may not like the anwer he gets.
Also purely from this side of the Channel, enthusiasm for an art. 50 revocation is very, very limitied. One reason is it may be purely procedural. May steps down, some soft Brexiteer is the next PM, he is conciliatory with Labour so the hard Brexiteers in his party wake up from their wet dreams of Imperial power, they hammer out a common position, and BANG, next art. 50 letter landing on the Council's desk, while Tory EMPs and Comission appointees try to pour concrete into each, any, and every real EU reform. The other reason is, have we endured this shit for three years just so Boris Fannybaws Johnson and Jacob Reek-Fuck can go on and on and on how everything bad in the world comes out Brussel's ass and how everything in the UK would better outside the Union while their constitutencies receive fat Cohesion Fund subsidies and they call Uncle Zbiginiew for their next plumbing job, cheap? Please, we've about had it.
