Congratulations, May, you've become Ted Heath 2: Electric Boogaloo.
Though may I offer don't-count-your-chickens advice--Labour could just as well get too cocky and blow it in the other direction, and I'm not even saying so from an anti-Labour standpoint. Heck, even with a seat plurality *they* could fall short of a majority, and here we go again, *three* elections triggered within the space of a year or so...
Yeah. Labour *cannot* be the ones to call the next election. Plain and simple. I'm not fully aware of the mechanics of calling an election without a Government or a no-confidence vote, but Corbyn and Labour simply can't risk being perceived as opportunistic and inflicting ~another~ election on the UK public.
After all, that was what poisoned May's campaign from the very start this time around.
The constitutional position is relatively clear. Theresa May is and continues to be Prime Minister until she either resigns or the House of Commons demonstrates it has no confidence in her.
If Mrs. May thinks she can command a majority in the House, which she could with the support of the 10 DUP MPs as well as her own party, then she will form a government and present a Queen's speech (which sets out the proposed government legislative programme). If the House passes the usual motion in favour of the Queen's speech then the May government has demonstrated that it has the confidence of the House.
If the House rejects the government programme or passes an opposition amendment, Mrs May would, under the traditional constitutional conventions, have had to either advise another dissolution or resign. Normally, either way, the Leader of the Opposition would be asked if he could form a ministry with the confidence of the House and if so would be appointed Prime Minister. Of course if the new Prime Minister proved over optimistic, he would then have to ask for a dissolution, which would probably be granted as no viable government could be formed in the present House.
Under the current fixed term legislation, a government defeated on the Queen's speech might either resign immediately or wait for the prescribed formal procedure to be followed.
