> if it passes, there will be something tied to the bilateral referendum in 2027/28 to try to supersede it
This is my thinking, too. If it really comes down to Chexit-or-nothing, we’ll have another referendum.
Well there's anyway going to be a referendum about the bilateral. (which is why I find the initiative somewhat stupid, you can vote on the real deal in a few years, about whether people want or do not want to have agreements with the EU, instead of hiding it behind a fake/emotional reason)
That was the UK's thinking, too. "We won't have a hard Brexit! Of course they'll negotiate a plan!"
