Brexit is a Conservative Party policy-idea that got out of hand. The collapse of the centrist and liberal Tory leadership created a vacuum for hardliners within the party, in the right-wing media, and in other smaller parties to occupy that space, and call for the reinvigoration of British exceptionalism through Brexit. Unfortunately, a political and constitutional crisis besets the United Kingdom, reducing the reality of British exceptionalism to Little England isolationism.
