The EU have got a lot of cards in all of this:
(1) The referendum might yet not take place - if the EU can talk Cameron out of having it by the backdoor.
(2) SHOULD the referendum take place - it will be timed to be on a great weather day, but out of main holiday season. I suggest late September 2017. The reasons for this will be that the sort of person who can only be arsed to vote when it’s nice outside - are the same people that would vote to “Stay In” and many of them - the same people that voted Tory at the last minute back in May.
(3) Should the referendum be an “out” result - The government backed by the EU will argue that less than a 2-1 majority to leave, means we should not turn the entire country upside down over such a narrow result. “Go have another referendum” we’ll be told - just like Ireland.
(4) Should the result be a clear 67%+ - The same argument (3) applies - only this time it will be of the ENTIRE electorate, rather than the score just in of those who voted. In other words, a “low turnout” works in the EU’s favour to stay in.
(5) So… We’ve got a 70% out of the entire UK population who want to vote “Out”… The EU make the entire referendum result “unlawful”. If we “press it” - we will be in breach of Brussels directive, and heavily fined. If we accept that we “lost” with the huge poll to “leave” - we can have this minor concession from Brussels “Absolutely Free” as a show of goodwill. Perhaps they’ll reduce our contributions into the EU by 10% whilst the Conservatives remain in office. Cameron resigning therefore - won’t be allowed either. An attempt to “Crown” Osbourne at this point will have riots on the streets - A general election will have to be held a month later instead, which may well see Tatton fall to an independent - as it did when unseating Hamilton for Bell a few years ago.
(6) We decide to press the result - the EU sanctions us. They will actually call it a “retractment of standing trade deals” though, as if it was always implied that “leaving the EU is to sanction one’s self.”
(7) If the Conservatives are still in power by this point (no reason to suspsect why they wouldn’t be) - That will be the end of it. We are still in the EU, but under sanction until we accept whatever new reparative scheme that Brussels decides to throw at us - for trying to throw off the yoke of supression.
Meanwhile, what chance have the “Out” voters got? - If 4m votes only got UKIP one seat - then I’m thinking that 40m votes in favour of “leaving the EU” will still be 10% short of the target - as far as international recognition is concerned.
America want the same as the EU want. No help there then.
There are not enough of HM armed forces left to stage a coup either. No ‘1789 France’ or ‘1776 America’ revolution for us either.
