<h1>Regional opposition leader warns state election could topple national ruling party, urges voters to change both levels</h1> A regional opposition leader asserted that upcoming state election results will destabilize the ruling national party at the Centre, linking its survival to support from a key regional coalition partner and another regional ally that helped form the current government. Speaking at a rally for the opposition bloc, the leader urged voters to change both state and national fortunes, accused the national government of causing migration from the state, questioned its role in inflation despite recent tax cuts, and alleged it was damaging trade and international relations, also mocking the party's use of secondary and consultant-backed campaign teams.
