I disagree with your answer since we would still trade with the EU.
It wasn't my answer, but the CBI's who you will no doubt be aware are the leading organisation representing British business. So somehow you, Jakswan, apparently know better about the benefits of EU membership on British trade, businesses and industry than the CBI, whose members are of course involved in ... err ... British trade, business and industry.
And the £60-70 billion benefit isn't the values of trade with the rest of the EU, but specifically the additional benefit we get from being an EU member and therefore being able to trade as part of a free trade area. Leave the EU and that benefit is lost, unless of course you agree (like Norway) to be part of the EEA but outside the EU and then of course the contributions to the EU will kick in again and you will have to abide by pretty well all of the EU regulation.
But you agree we send the EU £250 million a week.
And get £1 billion benefit a week in return - sounds like a no-brainer.
Assuming we can't negotiate a free trade agreement like Mexico
Mexico's deal with the EU is on the basis of supporting developing economies, in other words to slowly lift up developing countries and therefore increase the market ultimately for trade from the EU. There is no way that the UK would have the same kind of deal because it isn't a developing economy ... unless, of course the economy tanks so much from no longer being part of the EU that we become classed as a developing economy
also the tariffs go both ways can't see BMW etc being too happy with that.
Indeed, which is why BMW, and other major investors, will pull out of the UK and relocated to another part of the EU to ensure they benefit from the 90% of the EU market that isn't in the UK, tariff-free, rather than just the 10% that is the UK and pay tariff on the remaining 90%.
