The Taxpayers' Alliance has done its sums and calculated that EU membership is costing Great Britain £120bn per year. (Link)
Let's put that into context. It's three-and-a-half times our defense budget, or one-and-a-fifth times our health budget (and the NHS is the largest employer in Europe) or two-and-a-half times the education budget. In terms of public spending only the social security budget at £146.5bn is larger than our EU membership cost.
Is the EU really worth it?
