For those still trying to decide, the scare stories around the future economy are just that, stories.
You can do your own research where you will find that the UK/EU trade has fallen every year since 1999, and that trade runs at 1-2 in the EU favor.
That over 90% of British businesses do no trade with the EU yet are restricted by their rules and red tape, and that trade with the rest of the world not only outstrips that with the EU but is growing rapidly.
You can look into just who is telling you these scare stories and ask yourself do you believe these people ?, besides those "Experts" who wanted us to join the Euro there is Call me dave, who stands on the "Reforms" he won knowing full well he got nothing, a bunch of bankers linked by a company ( Goldman Sachs, google them for a tour of the dark side) behind every financial crash in the last fifty years, and the good old BBC who besides being a club for kiddy fiddlers has been funded to "Promote EU matters" to the tune of millions despite external funding being against its charter.
Ask yourself if you believe the nonsense that European countries ( Not the EU ) will no longer want to trade with us, one of their biggest customers.
The economy is a smoke screen to hide the real issue, do you want to live in a country run by whoever you choose to elected, or by an organisation run for the benefit of others with you having no say.
