Now comes the joke of the day. In case you voted out not just for patriotic reasons (hope most of you are sober by now), but to stop immigrants then you're going to be surprised. In order for "free" UK to negotiate trade deals with EU you'll need to accept everything non EU countries already have to accept as part of the deal. That means influx of immigrants too. In bigger quantities than when you were able to blackmail EU and get what you want. Ask Iceland what kind of an agreement they have and don't think for a second you'll be in a better place, because you won't.
Also, Chinese said you won't get shortcut for trade agreement with them. They'll treat you as small country now, which you essentially will become in next few years when your "brothers" jump the ship. You were their entry point in EU, just like you were for other superpowers. Now that you lost that privilege they have no fricking use of you.
But it's cool and dandy, right. You probably think it is 19th century and good old commonwealth will come and save you, that Canada, Aussies and India will help you and make Britain great again. Good luck with that...
Delusions of grandeur got you into position you're currently in, you better have something to back those claims otherwise you're fucked.
Also, in case you crash and burn which probably won't happen but if it does, you're going to be taken back in EU like you're Romania or something. No privileges whatsoever and they'll give rats ass about your national identity. You've played your cards, bet everything, now you have ONE chance to make this right. If you fail, you'll join eastern Europeans in their misery.
