Economics is complex. Free trade is more popular with the elites than the masses, but on that one, the elites have a better grasp of the economics. Still I doubt the majority in Britain want to bag the EU, at this juncture. Do you have a relatively recent poll on that? They do want to keep the pound sterling, and it has been kept.
Personal interaction with family members....
But this poll is an inkling...

The death penalty in Britain was suspended in 1965 and then finally abolished in 1969 despite strong public support for its retention.

The MPs do regard themselves as "elites", and the population lets them get away with it.
Several family members think we vote on too much stuff here in the US... and we shouldn't since "the politicians know better"....:^)
