(Yet another reason to dismiss the idea of Elected Head Of State idea. Whether directly/college-'elected' or appointed by the PM, depending upon which country you want to emulate, I think it shows that the ultimate Sortition method of 'accident of birth' (with fallback options) turned out better than than many of those put into power by electorate/selectorate/general political repositioning.)
I think there are already rumblings within the Tory party about (despite convention/1922 rules) deposing her, but hard to tell how much of that is "the srong person won" before considerations about what she and the quasi-chancellor just did (or did not!) do. There are also Labour calls to recall parliament to 'deal with things' (it's being Party Conference season, Labour having had theirs, Conservatives probably still trying to work out who has sent back RSVPs in a negative manner, not sure when and where LibDems/ScotNats/Plaid/others will (or have had) their get-togethers. I suspect that there could be enough Tory rebel-rebels to tip the balance, right now, if there was a Commons vote of no-confidence and nobody much more than the DUP[1] balked at it for ideological reasons. This doesn't spark an Election, though ((ninjaed!)), probably just roll up a new grudge-match amongst a new set of Tory leadership challengers, assuming party-defections and/or semi-voluntary by-elections don't tip the balance of power to a different party.
My take on the financial issue is that it was a "go fast and break things" philosophy, being applied to put a stamp on the new top-table/front-bench pairing's ascendance and rapidly reshape the financial landscape. Perhaps the upper level tax breaks were supposed to help gain sympathies from those with direct (as opposed to trickled-down-upon) interest in the movement of money. It might even be going 'to plan', but only if the plan is a lot more radical than I'd believe could be intended. Like to raise exports, of anything we still can actually export, at the expense of basically everything else.
It's not looking brilliant, though, in either execution or justification. Moody's looked like it was going to downrate the nation by a notch or two, last time I heard, which certainly won't help.
[1] I think they're still supporting the Tories, not yet been significantly put off by something that offends them. Like any vestige of human decency.
