"Once a plan is in place"
Such a statement pretty much shows why the market exploded... There is no plan, there never was a plan beyond leaving the EU... So now we have 2 years and 3 months of uncertainty for apparent freedom from, well I'm not actually sure what freedom or who had our country in the first place...
Should Scotland hold a second referendum they will leave... They stayed due to the EU membership, why would they keep within the turmoil when they want to remain?
Northern Ireland has a similar situation, only made worse due to the border with the Republic... They could well unify due to the massive complications they will encounter from bring out and the majority of areas also wanting in...
Cornwall council is my favourite thing out of this, as they've asked the government to confirm that any EU funding they will lose (circa £60m over 10 years) is kept... Where's that money going to come from? What other areas of the country have had their voters forget how much the EU supports certain aspects of the UK?
It'll get messy, very messy before things stabilise...
