So this vote that Mrs May lost, I'm assuming it is some irrelevance

Ok, so it’s it’s March 28th and there’s one final
chance for parliament to vote through her deal (via a short extension) or face no deal.

How many non-ERG members vote down her deal, in your estimate?

No. Y'see that's one idea you need to abandon. No Brexit simply isn't an option for anyone anymore. Neither major party could electorally survive not leaving the EU and - frankly - the last thing the EU wants is us still in as a deeply resentful, disruptive and destructive force. One way or another, we're leaving.
Now you could certainly argue that whatever deal is done is not true Brexit or BRINO or whatever, but the fact is that No Brexit (and a second vote) are actually the things that are now definitively off the table.

I've no idea what the political arithmetic would look like at that point (or what Labour might do).

But her deal would still be Brexit. It's not a Brexit I'd particularly favour, but it is Brexit. We would leave the EU.

Like I say, there is no option of 'No Brexit'.
