If that's the mindset then they could hardly be more mistaken. Such industries and the people who work in them depend on trade more than any others. A lot of Britain's factories are owned by firms from Japan or India who set up in the UK specifically because it was a good place within the EU to do business. In fact of the socio-economic groups I think it's the C2s (skilled manual workers) who gained the most out of EU membership.I think the mindset people around here had, especially since the steelworks closure, is that it couldn't really make things any worse.
That said, I think the DE group (unskilled manual labour and long-term unemployed) gained the least from it. According to a poll by Lord Ashcroft, though, the C2s were just as pro-Brexit as the DEs were.
Chuka won't stand for Labour leader. The reasons he pulled out last time will apply to any and every leadership contest in the future as well. If he did I do think he would do considerably better than Kendall did, but I don't believe that it would be enough to beat a candidate from the left of the party.
Personally I'm torn on Tim Farron's position. It's certainly true that there are those who would wish for the UK to be part of the EU (and I would count myself among this group), and it's certainly true that there are no other parties in England and Wales that can represent this view. Claims that such a viewpoint is undemocratic and untenable are about as reasonable as claims that UKIP should stop saying they want the UK to leave the EU if the vote had been a tad under 52% to remain. In other words, not. That said, I don't see that approach paying off as it's just not going to happen, and as such would much prefer the party to be pushing for the "in the EU in all but name" position (free movement of labour, in the free market, be a member of all the other related European institutions, sign international deals alongside the EU and so forth), which is a much more likely outcome and probably more productive in ensuring the UK gets a relatively neutral result from all this and preventing a terrible one. It might win less votes, though.
