We must have a second referendum

I've not posted on this blog for ages, as I became very busy finishing off the MA in History that I was studying via distance learning. Now that is finished, and we are facing probably the most tumultuous few weeks in British politics since the second World war, I feel I ought to post something about Brexit, starting with the political events of the last few days.
Last week, various parliamentarians, including the Speaker, Jon Berkow, were accused by elements in the media, as well as many on social media, of hatching a coup to thwart the "will of the people", when the Speaker allowed an amendment to be added to the government's finance bill which would force the government to come back to parliament within three working days, in the event of Teresa May's withdrawal agreement being defeated, with a statement about how they now wished to proceed. This accusation was utter nonsense. In a matter of such vital importance, it was quite right for the speaker to allow parliament (which represents the whole country) to put some pressure on the government (which, being a minority government, represents less than half of the electorate). During the referendum campaign, many brexiters opined that parliamentary sovereignty was the very thing which they felt was threatened by the UK's membership of the European Union, so it is hard to see why they would complain about parliament trying to exercise some kind of check over the executive in these circumstances. (Some brexiters even called this an unprecedented seizure of power by the legislature over the executive. I would suggest that Charles I, were he still around to comment, might not agree with them on that.)
Last night Teresa May's withdrawal agreement Bill was defeated, by 432 votes to 202, the largest defeat for any government in parliamentary history. Jeremy Corbyn has tabled a vote of no confidence in the government, which will be debated and then voted on today, although the government is expected to survive thanks to the support of the DUP. After last night's defeat, Mrs May said that she would reach out to other senior parliamentarians across the house to try to find out whether there was some form of deal that could be supported by a majority in the house, which could then be put to the the European Union.
However, in this afternoon's Prime Minister's Questions, she stated that any new deal must involve an end to freedom of movement. This shows that she is either in total denial, or is being completely insincere in her offer to listen to other parties. The EU have made it very clear that the current deal is the only possible deal on offer if the UK insists on leaving the single market and customs union, and there is no way that Britain would be allowed to stay in those institutions if it does not accept freedom of movement.
For the past two years, Mrs May has let herself be guided by the misguided notion that it is her duty to take Britain out of the single market, out of the customs union, and to end freedom of movement, because, apparently, that was what most leave voters wanted when they cast their vote to leave the EU. This was a fundamental mistake because, as I argued in this post shortly after the referendum, even though many Brexit voters may have been opponents of immigration, the fact that the leave vote was only 52% means that the anti-immigrant brexiters were undoubtedly only a minority of the those who actually took part in the referendum. There is, therefore, no mandate for insisting on an end to freedom of movement or membership of the single market or customs union. Mrs May's inability to see this could potentially lead this country to disaster.
There has been talk recently of a move within parliament to come together around a Norway style deal (something I argued for in the post just referenced), but if Mrs May is intransigent on this then there is no real possibility of it coming to fruition. If she survives today's no confidence vote, then we are left with only two options. Either a 'no deal' Brexit, which almost all forecasters say would be disastrous for the country, or no Brexit at all. Until a few weeks ago, I was opposed to the idea of a second referendum, but since these seem now to be the only two options (unless, against all predictions, today's no confidence motion succeeds) I have now become a supporter. I do not believe that there has ever been a majority for a 'no deal' Brexit. Indeed, the latest polling indicates that staying in the EU is now the "will of the people". It would, in fact, be an affront to democracy if the government were to take us out of the European Union with no deal, without first checking if that was what the majority of the British people wanted.
