Personally, I think the whole Brexit referendum idea was a plan designed to show that players such as Farrage and his followers were a small minority in the grand scheme of things, with no real support from the masses, and could therefore safely be ignored forever after.
Ultimately, as shown, they were well out of touch with the people they represent . .  it was a close result I admit, but it was a result I believe they never in their wildest dreams envisaged 
 
Cameron waved as he walked away from the monumental mess he'd created, but who else that contributed to that mess is still in office and doing 'very well thank you' ?
