DMK leader MK Stalin on Saturday said the AIADMK must support the no-trust motion against the BJP-led government at the Centre, utilising the available opportunity and establishing its right for the Cauvery waters.
In a statement, he said had his party been in the Lok Sabha it would have announced its decision to support the Telugu Desam Party's motion.
Stalin said Chief Minister K. Palaniswami should announce AIADMK's support for the no-trust motion and apply pressure for setting up of the Cauvery Management Board (CMB) and Cauvery Water Regulatory Committee (CWRC).
Out of the total 39 Lok Sabha members from Tamil Nadu in the Lok Sabha, the AIADMK has 37 members while the BJP and PMK have one each.
Stalin said the Supreme Court on February 16 had ordered the Centre to set up the CMB and CWRC within six weeks of its order.
However, the Centre has been delaying that keeping in view the ensuing assembly polls in Karnataka which is not enthusiastic about the Board.
Stalin said Prime Minister Narendra Modi was not willing to meet the representatives of all political parties from Tamil Nadu in the Cauvery river water issue.
On Thursday, the Tamil Nadu Assembly passed a unanimous resolution demanding the central government to set up the CMB and CWRC as per the Supreme Court order.
The AIADMK on Friday sacked spokesperson KC Palanisamy after he urged the party to back a no-confidence motion against the Modi government if it did not take a favourable stand on the Cauvery issue.
A statement issued in Chennai by the party's Coordinator and Deputy Chief Minister O. Panneerselvam and Joint Coordinator and Chief Minister K. Palaniswami asked party members not to have any contact with Palanisamy.
According to the statement, the former MP acted in a manner bringing disrepute to the party.
Following KC Palanisamy‚Äôs sacking, senior leaders indicated that they would most likely align with the BJP if the motion is moved on the floor of the House.
Speaking to reporters, Lok Sabha Deputy Speaker M Thambi Durai also hinted that the AIADMK was unlikely to support the no-confidence motion against the Central government.
