OK so let's seriously analyse the current situation then.
Doesn't look like the Moggies can get the 48 letters together, so Theresa stays.
She's got to get her draft deal through the EU, then Parliament
The EU may be difficult, and Parliament even more so. The Moggies, DUP and the opposition are likely to vote against or abstain.
Apart from the Moggies they've all made clear they will not allow a 'No Deal' result.
So other options will be provided - postponement, amendments to the deal, new referendum etc. We don't know.
The deal is of course 'business as usual' for the next 2 years (or more). Then they sort out the future arrangements which it is clear will involve some sort of permanent Customs Union with the EU. That will also come with conditions. May is of course a Remainer after all.
So, if 'No Deal' is off the cards, and the only choices are Draft Deal followed by Permanent Deal with more conditions, or Remain in the EU as it, what do you vote?
