You'll be the new Norway! There's just a couple of details you need to sort out first though. I strongly advise you to increase your oil production and decrease your population by about 55 million. And try to get used to paying 50% in tax. You will also get a great feeeling of solidarity when you eat your British produced fry up heavily subsidised by your own tax money.
