Rachel Sylvester makes an important point in The Times:
Democracy is about persuasion rather than obliteration and there are rules underpinning political conflict that don’t apply in military combat. The prime minister seems to have forgotten that, far from being the nation’s commander-in-chief, he is only “first among equals” in the cabinet and depends for his power on the House of Commons. The scorched-earth approach being pursued by No 10 will make it almost impossible to unite the Tory party, let alone the country, when the skirmishes are over.
There is an autocratic streak in a lot of current politics that should concern anyone who values democracy.
