Chennai: The AIADMK on Friday expelled party spokesperson KC Palanisamy after he urged the party to back the no-confidence motion against the Narendra Modi-led government.
The decision was reportedly taken by AIADMK coordinator O Panneerselvam and joint-coordinator Edappadi K Palaniswami.
Terming his expulsion undemocratic, Palanisami claimed he was not offered given any explanation regarding the decision.
Palanisamy had earlier suggested supporting the TDP and YSRC if the Centre fails to constitute the Cauvery Management Board and the Cauvery Water Regulation Committee.
Earlier today, the TDP walked out of the ruling NDA, with its 22 lawmakers - 16 in Lok Sabha and six in Rajya Sabha. While this may not affect the government in the Lok Sabha, it could pose problems in the Upper House.
The decision was taken unanimously by the TDP politburo this morning.
Jagan Reddy-led YSR Congress and All India Majlis-e-Ittehadul Muslimeen (AIMIM) also pledged to support the no-confidence motion against the Modi government.
The BJP and TDP had been treading on a thin line after the Narendra Modi government did not allocate additional funds for Andhra Pradesh.
