Ok, this is all very dramatic.
But.....
Isn't there basically only the one deal, which was negotiated between the UK and the EU and which the EU says cannot be re-negotiated and which has the "Backstop" that can also not be re-negotiated? So, all this hoo-haw is for.... why? Are they going to vote FOR the last PM's deal (aka, the only one in town) now? If not, what is the purpose of all this?
