The Tories are wedded (atm) to Brexit, however, if they ever did U-Turn on it, would be a huge issue for Labour... who have been beyond weak on the issue, they 'd either have to oppose re joining (or trying too) the SM or themselves change, like the 1p tax cut.
Agree... EU don't want another Swiss style deal.
Tories dropping even further in the polls, following the budget, anything is possible if the country turns pro EU.....
