not honoured by any party they are in breach of their democratic obligations in taking part in the referendum which was agreed by all to be by a one-time yes or no decision by a majority of voters.
The UK can in future vote into power a party with the object of reversing this policy by putting forward a new referendum for all the people to vote again. But until that occurs all parties should honour the original referendum result - unless of course criminal cases are proved to show that the voting decision was somehow fraudulently arranged.
Let us all be absolutely clear - if the decision of the people in the referendum had been to remain in the EU there would have been no party claiming that we should ask the people again just to make sure that's the result they wanted!
The agreed democratic process of the referendum was to accept the majority decision of the people.
Of course there are a whole series of different ways in which we could be said to be leaving the EU but there is not one of them involving the words "we wish to remain in the EU" or "we revoke our decision under article 50". The Government of the day should already have pushed through Parliament an agreed method of exit and be in the middle of an agreement as to the future traing relationship with the EU - the Tories just completely failed to take parliament with them and so I suspect we will have to wait for a new General Election to force Parliamentarians to pledge a particular stance.
The original composite Labour Party motion on Labour's Brexit policy did not include the word Remain or the word Revoke. It did say they should keep all options on the table including supporting a public vote - but this did not say that the vote would include an option to vote to remain in the EU. The latest letter from JC goes a step too far beyond the composite motion and I think there are grounds to say that they have breached the rules of the party by making that statement.
If the Labour party includes the "Remain" option in its manifesto for the next election whether it has secured a change in party policy at the next conference or not then I for one will be resigning my membership. This is not because I support Brexit but because I uphold the principle of honouring a contract entered into between Parliament and voters and any proposal to renege on that contract can never be valid.
This move by the power brokers in Labour is all about breaking up JC's Labour and ensuring it never get's into power, which of course it will never now achieve.
The biggest mistake JC and like minded people have made is to assume that the British people voted for Brexit only if their economic position remained unchanged. They cannot know why people voted for Brexit and they should not assume that economics was their first reason - in fact the future economic position of Britain outside the EU is totally uncertain and so economics should not even be considered.
