It's on its way Pete, make no doubt about it.
We've entered a "phony war" period waiting for a Government to come up with a timing and strategy for Article 50 and subsequent actions. We sort of have a timetable but no strategy (cunningly phrased as no running commentary), the nearer we get to the trigger of Article 50 and no evidence of a strategy the worse it will become.
Of course, the Government has seen the independent Bank of England engage in huge quantitative easing (again) and a further reduction in interest rates to stave off the immediate impact (very Keynesian

)but let's not kid ourselves, they've just kicked the can down the road a few months.
We have no idea what post Brexit will look like other than we will not remain in the Single Market - so on what terms do we trade with Europe? WTO? No-one knows, least of all the Government.
