It's a discussion which tries to bridge the gap still there. Out of 1.1 trillion Euro over seven years still 70 to 80 billion needs to be found. That's 10 to 11 billion Euro per year (or 8.5 - 10 billion GBP). Hardly worth squabbling about as it's only 0.07% of the E.U. yearly GNI, it's even less than BoJo's famous 'bus unit' of GBP 350 million / week.
