Actually our net contribution after the UK 'correction' is applied is significantly less than Germany, France and Italy.

My understanding is that if we vote out Article 50, the never yet used process for withdrawal from the EU, will apply. There will be a maximum of two years for the UK to disengage itself from the EU, and we will NOT be represented on the committee/group which will make the decisions on how this happens. It was deliberately designed, and we signed up to it, to make exit unpleasant and difficult. Howard's comments are clueless, there is no precedent for a country leaving. But I agree, I don't think there will be any spite involved, we will have to get on and because of 40 plus years of membership, our economy is pretty well integrated into the EU, no one will want to make life more difficult for the people who actually make things and deliver services and pay the taxes which pay for politicians to **** around.
I sincerely hope you are nice and warm at the game today.
