I am completely unconvinced by Dave's point that they would be unwilling to trade with us. Believe me the pressure on Germany's Chancellor from BMW, VW etc. to establish a free trade agreement with us will be tremendous, we are still the 5th richest nation on earth. The same goes for pressure from French car manufacturers and wine growers or holiday businesses in Spain. We run huge trade deficits with France and Germany so it is very much in their interest for trade to continue.
I think hatter is dead right here. And for the same reasons, big business in the UK will be equally forceful in insisting that we remain part of the European Economic Area, like Norway and Iceland. So Prime Minister Johnson will be forced to take the UK into the EEA, meaning we will continue to make a significant contribution to the EU budget, as Norway and Iceland do, and we will be required to allow the free movement of EU citizens in and out of the UK. In other words, the only significant difference between being in the EU and being in the EEA is that we will no longer have any say in drawing up the rules.
Let's not forget we spend £16bn a year on EU membership and only get a small fraction back.
Even the Leave campaign now accepts that this figure is a gross misrepresentation - and that's putting it politely! We get about half of that back, in the rebate which Thatcher negotiated all those years ago, and in grants and subsidies to agriculture and business. Our net contribution to the EU is about £8 billion per year.
In terms of the EUs own figures, the single market only adds 2.4% to national GDP across the EU.
Indeed. So as the UK's annual GDP is £1.7 trillion, 2.4% of GDP adds up to a cool £40 billion! So if we leave , we face losing £40 billion a year in order to save £8 billion.
I've got a horrible feeling that it could happen. But if it does, it could get extremely messy after that. Take the two year period in which the terms of our exit will be negotiated. Prime Minister Johnson will be personally committed to those, but at least two thirds of the MPs in the House of Commons are 'Remainers', so they will make it very difficult for him. And to anyone who says 'the people have spoken and Parliament must respect their wishes', every MP but one (Douglas Carswell, Clacton) will turn round to their constituents and remind them they they elected him/her on a party manifesto which stated a clear commitment to remain in the EU.
What a mess. And who got us into it? D Cameron.
