I heard a person talking about the contribution on the radio.
He made the point that each country contributes an amount to the EU budget, and is entitled to claim from that budget, subject to certain rules and agreements that all the countries sign up to. He said that we have agreed to contribute 1% of our GNP* (except that we get a rebate) and that UK has had a more successful year than was anticipated, therefore our agreed 1% of the larger amount will be greater than was anticipated.
(*though I thought I had heard earlier that the contribution was based on VAT revenues)
He likened it to a person paying x% income tax. If he has a high-earning year, he pays more tax than if he has a low-earning year.
He also made the point that if C.A. Moron did not know how much UK had earned, and therefore what 1% of it would be, then he should have known.
I understand C.A. Moron has not denied that he will pay the amount due under the terms that UK has agreed to, only said that he intends UK to be a late payer.
I wonder if anyone can point out any inaccuracies here, or if it is just Daily Mail meaningless bile.
