I think you have fundementally mixed things up here. The UK is (was) the second-largest economy in the EU. If you want to talk about percentage contribution to the EU budget the UK was a net contributor of 8.5 billion pounds (after "rebate") more than it received from that same EU budget that totals around 125 billion pounds. So they put in about 7% of the budget and get about 10% of the votes. Definitely a deal that favors the UK, but let's please stick to reality and facts here.
