Defection as Party‑Realignment Catalyst

A high‑profile ministerial defection or forced sacking (here Robert Jenrick’s move and Badenoch’s response) can rapidly rewrite narratives about competence and identity for both the incumbent party and insurgent challengers. Because modern politics is attention‑driven, such episodes can convert personality disputes into durable partisan realignments if activists and platforms amplify them. — This raises the risk that single elite moves—leaks, purges, defections—can accelerate party fragmentation, change policy trajectories (e.g., migration), and reshape 2026 electoral coalitions in the UK and comparable systems.
