Well I certainly didn't say that anyone had changed their mind.
Basically, the vision for Leave needed to be thought through maturely, before offering a simplistic IN/OUT ballot paper. The likes of Johnson and the ERG just said anything they could to get people to vote Leave. There were promises of having our cake and eating it... how we had all the cards... the EU will be begging to do a deal with us - the easiest deal in history... billions of pounds a month for the NHS.... etc etc. What a morning on 24th June 2016... Yippeee... Freedom.
Then over the coming years, their confidence waned - reality struck them as they tried to find a way to find a Brexit deal that was compatible with the GFA - and, cutting a very convoluted story short, despite dozens of attempts, they couldn't find a solution other than putting a trade border down the Irish Sea (despite categorically saying they wouldn't)... and lumping Northern Ireland in with the Republic. What a dog's breakfast.
Of course, as it dawned on them that "Leave" had made promises to the British people that could not be kept, they got increasingly desperate, and lashed out at the EU to try to absolve themselves of blame... but the people who constituted that referendum, and then enticed the public t vote Leave, they are the ones to blame.
Blaming them for what Reg?.... Upholding a referendum result that no one seems to regret?
