The undeniable truth is that there in no consensus amongst the UK's politicians for any single outcome.
Labour MP Hilary Benn has today joined the ranks of countless others who apparently have very severe hearing & sight problems - by submitting an amendment which suggests the following:
reconsider Mrs. May's deal
2) leave the EU with no deal,
seeking to renegotiate the deal or
4) holding another referendum.
The 1st and 3rd suggestions have already been certified as dead & buried - thanks to a massive rejection by the UK Parliament and an even bigger rejection by the EU government, which reduces the options to a choice between 2 or 4.
Since the vast majority of MP's are united against the no-deal scenario, an extension of 6 months of Article 50 to allow for another referendum would be my bet.
