BREXIT

[VNA]

But why choose the uk over any other countries.

All you need to know is that if we are outside of the single market and the customs union they will leave.
Previously they were stuck with quotas and tarriffs. 

Then there are parts issues.  Take BMW's mini crankshaft,

A cast of the raw crankshaft – the part of the car that translates the movement of the pistons into the rotational motion required to move the vehicle – is made by a supplier based in France.
From there it is shipped to BMW’s Hams Hall plant in Warwickshire, where it is drilled and milled into shape. When that job is complete, each crankshaft is then sent back across the Channel to Munich, where it inserted into the engine.
From Munich, it is back to the Mini plant in Oxford, where the engine is then “married” with the car.
If the car is to be sold on the continent then the crankshaft, inside the finished motor, will cross the Channel for a fourth time.

The reality is that if we leave without either a single market commitment or a customs union then they will leave.  They must have quota free and tariff free access to the whole EU market, and the whole of their manufacturing process must be within the EU.
