> The Brexiteers are the party of the unwritten British constitution as it existed from the Glorious Revolution of 1688-89 until Britain’s accession to the E.U. in 1973. This is the tradition of “parliamentary supremacy,” as John Locke called it, or “parliamentary sovereignty,” as it more often came to be called.

Not sure I'd be sending this article around as the canonical last word on Brexit after the prorogation and today's ruling on it.
