1) If Parliament would vote today (very unlikely) for exit with no deal, she said that would become immediately Government policy.
2) If.... 1/n
3) Parliament will then vote on Thursday whether it favours asking for a date extension... 3/n
5) If Parliament votes for the extension, then she said that it would have to choose among 3 alternatives: a)... 4/n
b) convene a second referendum
c) vote for a different deal, specifying the general terms of that deal.
If, as it seems (am I wrong on this?), there is no majority for any of these choices, the impasse would justify a 3d WA vote... 5/n
