"Yet another unintended consequence of Brexit has been discussed in the press today."

It is as yet merely a discussion. More sabre rattling from the Eunatics master class.

Perhaps their babblings should be rationed! Or perhaps they have been exalated and the ensuing musings are more correctly termed dribblings.
