OK OK. You have cajoled me into signing the damn thing. I wish they had defined what this "rule" is. It isn't in Article 50 of the Lisbon Treaty. I can't remember this article being mentioned in the IN/OUT campaign but I suspect we are all going to hear a lot about it over the next two years - which, by the way, is all the time we have got to negotiate a new deal unless ALL the EU countries vote to extend the period.
