Ulsterisation of English politics

English local politics are polarizing into territorially signalled identities—flags, rituals and municipal gestures—that mirror Northern Ireland’s sectarian public geography. Party fragmentation and devolved‑nation separatism combine so that cultural symbols become levers of political disintegration rather than downstream epiphenomena. — If correct, this reframes UK politics as a rapid process of devolved fragmentation with constitutional, security and electoral consequences across Britain.
