It's a bit of a dogs breakfast of a largely protest vote that doesn't really mean anything as perhaps only 50% of it (which itself is only 40% of the population) matters

The Brexit party could represent only 16% of the voting public
Only 2/3rds of that number actually want a no deal
And already, half of the possible 16% will go back to their parties in a GE
