Corcory, your post doesn't make sense to me.
It's a pity you didn't look into the £350m thing a bit more ...
I did which is why I wrote,
I knew the £350million a week was wrong ...
And £350million was not the gross figure, because the rebate was taken off at source and was never sent. UK's 'bill' last year was about £248million (gross) and after grants etc., the total cost to the UK was £136million approx., (net).
The assumption I made was based partly on logic – if we left the EU then we wouldn't get any grants from the EU, that's obvious. Leave said, in effect, the money we save by leaving will go to the NHS. It follows there would be nothing in the pot to give to the Farmers, etc. The assumption was based partly on people I've spoken with, such as one of our grandsons about an hour ago. He voted Leave because he believed the £350million a week would go to the NHS and no one else.
As for your other points, Patty, twofingers, Kaija and Peregina have covered them succinctly.
