Beddy - I disagree. With greater understanding of the issue and/or if public opinion changes, it is justifiable to have another referendum or general election to officially record that change. In the case where parties themselves are split on the direction, leaves a new referendum as probably the best choice. But to say we have made our choice we just have to see it through is not true.No doubt now things are getting difficult people will change their minds. You still cannot have another referendum just because things have got difficult. The choice was made and we have no choice but to get on with it.
Who knows maybe the EU will come up with something at the last minute that can provoke another referendum, but not as it stands at the moment??
I don't think it will happen as it will be political suicide of T. May and possibly lead to a fragmentation of all political parties.
