<h1>Opposition party elects new chair amid foreign interference claims, raising concerns over security, policy and election integrity</h1> Taiwan's main opposition party elected a new chairperson in a contested internal vote amid allegations of foreign interference, with security authorities reporting extensive social-media activity from accounts largely based outside Taiwan. The party holds a pivotal legislative bloc and faces scrutiny after recent recalls and controversy over measures perceived to weaken executive authority and favour foreign interests. The leadership change may affect cross-strait policy, defence funding debates, and candidate selection for upcoming local and presidential contests. Domestic officials urged vigilance against external meddling and called for protecting national security and electoral integrity.
