Every move by David Cameron, from the gagging of his pro-Brexit Ministers; the mobilisation of the officially neutral Civil Service on behalf of the Remain campaign; to the orchestration of the great and the good industrialists and retired Generals to write to the newspapers advocating Remain, shows that he has taken a leaf from the EU's playbook for running referendums. And the EU itself has always followed Europe's darkest and dodgiest historical precedents to either rig referenda, or overturn and re-run them if by some mischance they go the "wrong" way.
