The case for Brexit was built on lies. Five years later, deceit is routine in our politics

After five years, the biggest casualties of Brexit are in plain sight. Integrity and decency in public life are crumbling. Because so much of the case for Brexit is false, the political modus operandi of the Brexiters, now dominating our political culture, has become a refusal to accept responsibility for mistakes, overclaiming, deceit and sometimes outright lies to justify the unjustifiable. Once the electorate can no longer trust what they are told, democratic debate is denied. We have been robbed of a core right of citizenship.
