" 95% of UK firms do not export to the EU at all."
Well that would be true, but as 76% of those businesses are employ ONE person, the owner, we wouldn't expect them to would we?
"Despite the billions of pounds we pay into the EU, our influence is small and declining. Can't remember our votes in the council of ministers but its less than 10%."
The UK vote in the EU council is 8%, far higher than it is for other countries, more than double what it would be if votes were shared equally. So other countries have to lose influence to give the UK a larger vote.
The UK paid about 13 Billion net to an EU budget of 143 million euros, which basically accounts of just less than 10% but we pay in less than Germany, France and Italy.
"EU's share of world GDP is declining. It has gone from 30% in 1980s to 20% today and still going down"
Europe's share of world GDP is falling because the scale of word GDP has increased since 1980 (he year you get this figure from cause Daniel Hannan used it) for example the UK's GDP in 1980 was double that of China despite having 17 times the population of the UK. Now given that economies like this India and Brazil have increased rapidly this period of time they have contributed a far larger level to world GDP than before.
However, in nominal and real terms the EU GDP has got bigger, so we have a smaller % of the pie, but as the pie got a lot bigger, we still have more pie than we did in 1980. The EU is not declining.
If you want control of the fishing, ask the government or the member for the Fisheries policy that turned up to 1 out of 40 meetings in his time on on it.
The 30 other countries do not have the same deal that we do, even the Swiss don't even have a full free trade deal like we would need to continue to the same level,
I'm not going on picking your points to pieces, but you can vote on what you like, it doesn't mean that the reasons you have given are correct.
