To The Australian Michael Sexton is right to state that the essential issue of Brexit is the question of national sovereignty ("Plenty of spanners thrown into the Brexit works", 18/9). He could have added that the resumption of independence for Britain will be a profound victory for the principle of intellectual freedom, something gravely threatened by the EU's authoritarian attitude to legal issues. There must surely be an election to resolve once and for all the Brexit puzzle. We must hope that, firstly, the Conservatives and the Brexit Party will co-operate to maximise their joint success and, secondly, that enough Britons have been revolted by the dishonourable sabotage of the popular will, as clearly established in the 2016 referendum, to switch their votes from Remain to Leave.
