If Britain leaves the trade group, it will still have to abide by many of its commercial regulations but without any input and also cede a lot of global economic heft
A Brexit has nothing to do with regulations that British companies already manufacture too. It goes without saying that upon exit that they woud still have to comply to europeon standards if they wish to continue trade with Europe. The withdrawal from the EU is about taking back control of Britain's borders, and of British laws and the horrendous human rights drivel coming out of Brussels. No British citizen has ever had the vote on joining the EU in the first place, it was a vote back in the late 60's for joining a free trade agreement with a small contingient of Europeon countries. Switzerland and the Scandinavian countries seem to be doing remarkably fine on their own after having not joined the EU, and thank god the UK didn't join the disasterous Eurozone but kept the ? otherwise the British economy would have tanked with the fall of the euro.
