The French owning our electricity has nothing to do with the EU and absolutely everything to do with the Conservative sell-offs of the 1980s and 1990s, cheer-led by the kind of people who are lining up for Leave now.
It's also been said many times but the kind of de-regulating free market folk that the Leave campaign are typically drawn to would sign up to TTIP in a flash and it's the Brits in the EU who are pushing to get it done. Leaving the EU is zero protection from TTIP.
There's plenty of that persuasion that would shut down Port Talbot tomorrow because "the market" has spoken. The idea that old school protectionism will take over come Leave is pretty fanciful. It won't be Boris's style that's for sure.
And I'm not convinced that in the battle of the widget makers, the one not adhering to EU regulations is the one with the competitive advantage over the one that does. As the largest trading bloc in the world, EU regs are a very strong currency and guide of quality across the globe. I'm not convinced there is any evidence that manufacturing things to a completely new set of regs we have to make up is going to genuinely unlock any market for any British business.
