EU referendum: playing war games over UK future

16 December 2013 Last updated at 13:49 GMT

Britain's future in, or out, of the EU has been acted out in a political war game organised by a think tank.

David Thompson watched the Open Europe game in action and spoke to some of those taking part in the "negotiations".
