Net‑Zero Immigration Politics

A sudden collapse in net migration (here: UK ONS reporting a fall from 906k to 204k in two years) can become a decisive electoral variable by defusing anti‑immigration momentum and forcing parties to rework their taxation, public‑service and labour narratives. Whether the decline is structural or a measurement artefact matters politically: parties that built fortunes on high‑migration anger could lose their issue advantage even as new disputes (emigration, skills loss) emerge. — If major immigration flows reverse quickly, it will reshape party competition, culture‑war salience, and immigration policy design ahead of the next election.
