The true consequences of the out vote will not be understood until a final agreement is signed with the EU and only then can meaningful discussions start in earnest with other trading blocks, who will be waiting to see the relationship between the UK and EU before committing
Sad to say but the above applies to our political masters as well as the general electorate, as prior the referendum there was little discussion on what post-Britex would look like other than the campaign leaders spouting their nice to haves, without any prior discussions with the rest of the world.
The economy is the primary driver that sets a countries position in the world and being outside the EU the largest trading block in the world without a perceived good deal from the EU will be like shooting ourselves in the foot.
Here's a long shot; Other countries in the EU start to push for major reforms of the EU(France, Germany, Benelux) which may influence the UK into rethinking its decision and stay in, however that could take 5/10 years, the critical phase is the period 0/5 as we will be sailing in the sea of uncertainty the hurricane of the financial market.
Anybody else any bright ideas' ?
