Another flourish would be for a couple of hundred Commons MPs to quit parliament. After all in three years they have failed to implement the express will of the people so they are not doing their job. They are now in effect saboteurs.

That's for the Brits. Brussels could decide the EU now only consists of countries on a contiguous landmass and hence let go of Ireland. Backstop problem solved. They don't want Turkey in so the Bosporus could be regarded as a sea. One for the suggestion box.

Brexit is a typical scenario of over-privileged & over-jealous, over-idealistic being where they are not suited of being ! Like most Authorities their circles too are full of experts but none-who knows anything !

Tasweigen, Istanbul is on the EU side of the Bosporus !
I think you mean the Aegean Sea.

Basically Britain wants its independence back.
They no longer want to be subject to the Brussels Colonial Office.
