Since my last Brexit column, we have now had the judgment of the Supreme Court on the prorogation of parliament. The judgment is worth a read and deserves more column inches than I can offer here. The Prime Minister promptly let it be known that he profoundly disagreed with it. The leader of the house of commons and erstwhile Brexit ultra Jacob Rees-Mogg called it a constitutional coup (as if that wasn’t the pot calling the kettle black). But former Supreme Court judge Jonathan Sumption summed the whole thing up quite aptly when he said on the BBC that “one has to accept that if you behave outrageously and defy the political culture upon which our constitution depends, a lot of judges are going to be tempted to push the limits. And the trouble is, Boris Johnson has taken a hammer and sickle to our political culture in a way that is profoundly provocative to people who believe that there ought to be solutions consistent with our traditions.”
