Multiple outlets mark the 10th anniversary of the Brexit referendum, describing the result as a major turning point for Westminster and UK politics. They say the vote, held about a decade ago, delivered an “earthquake” effect, with political alignments and debates shifting substantially after the outcome was announced. The coverage frames Brexit as a lasting change rather than a short-term political event, emphasizing how the referendum result permanently alters the political landscape. One article uses strong language to characterize subsequent political developments in the aftermath of Brexit and compares them to governance norms outside the UK, but it still centers on the referendum’s broader impact.

Across the available sources provided, the core shared claim is that the Brexit vote’s result continues to be seen as a permanent inflection point in British politics. No additional, specific new facts are introduced in the provided excerpts beyond the anniversary framing and the assertion of long-term political consequences.
