Jo Cox's Sister: UK Political Division Now Exceeds Brexit Era

Kim Leadbeater, MP for her murdered sister Jo Cox's constituency, stated on the tenth anniversary of Jo's 2016 death that UK political polarisation has worsened beyond the Brexit referendum period. Cox was killed by a neo-Nazi one week before that referendum. Leadbeater's assessment carries weight: she occupies a singular position as a legislator whose family experienced the era's most direct political violence, now drawing a line from 2016 to 2026 and saying the trajectory has not improved.
