My apologies. I interpreted it as you saying that something is not on offer, and I’m asking who is doing the offering?
I think that many people would now agree that a renegotiated deal along the lines of the Swiss arrangement would be acceptable to a majority of the UK electorate. If the EU were officially asked for such negotiations, then I think it would agree. Ergo, if that, or something approaching that, is not on ‘offer’, then I can only presume that is because the UK politicians don’t want it and won’t hold it out as an offer to their voters.
