I don't think turning back now is politically acceptable. As the country is split, half of the population would be in revolt.
I think it's a waiting game. We need to be vigilant about the way the government wants to make a bonfire of EU regulations and challenge them. It would be helpful if we had an effective opposition.
As people see that there are no solutions which will satisfy the majority of them, they might very well be gagging for a second referendum in 18 months.
People need to change their own minds rather than having solutions imposed.
It's a mess, which could have been avoided!
