Whaaaaat?
Why?
In fact, why would we not if the national opinion appears to have changed?

Brexiters saying there can't be a second vote sound awfully like double glazing salesemen telling a previously underinformed and grievously misled old lady that it's too late to change her mind, she must pay, it's the law.

(It effing isn't the law. The law is entirely silent on the matter).
