Regreatfull in the delay on responding as I just keep getting very busy
You're missing the point: An elected MP and especially PM cannot abdicate his or her responsibility for the outcome of their policies, completely regardless of any political promises made – using their own judgment and then standing up to take the responsibility for that judgment is inherent in the position and simply cannot be fobbed off to an incidental referendum, regardless of circumstances!
Incorrect the PM dose not hold absolutel power in shaping the manifesto it is a party and cabinet position, the referenda was endorsed by parliament on both sides of the house
And out the window go all your attempts to construct a somehow still compulsory effect from it!
Show me where I have said it is “compulsory” you just cannot accept that the government said it would honour the results of the referenda, the position of remain camp is it’s all right not to honour election policy/ manifesto‘s if you do not agree with it. That gives the government a blank check to lie and bullshit in the full knowledge that the electorate will disregard their callings to honour policy.
The implication was: "Those who advocated for Leave have the responsibility to come up with an actual plan!"
Those Leave advocates have just completely shirked that responsibility, so the regular responsibility of all the elected representatives for the fate of the country kicks back in, and that is not optional, it is mandatory!
You still did not answer the question, your definition of the word “remain & leave”
The remain and leave campaign had no authority to have a plan for after the referenda, that was the job of government. Did the remain campaign have a plan to reform the EU as per the manifesto.
If years down the road from a referendum that decision turns out to be completely unworkable and the elected politicians turn out to be completely unable to deal with that situation.
In this case of Brexit you are talking about not coming to an agreement for the WA, the actual leaving of the EU is still achievable as it within the mechanism of article 50. The intent of leaving the EU is workable just not in way by agreement of both party’s EU/UK
it is in fact entirely proper and appropriate to put the then current state of affairs to the people again to either revise the previous decision or to confirm that the country is to be pushed over the cliff edge regardless of not having any workable plan, but notably with the voters now actually knowing the reality of what had just been an unrealistic fantasy before!
The cliff edge or working plan is their, you just do not like it. In the event on leaving the EU is WTO their is a plan on a no deal exit
