Congress candidates have won two seats and were ahead in 69, while the JD(S) was leading the table in 39 constituencies. DMK working president M.K. Stalin greeted the BJP and its chief ministerial candidate B.S. Yeddyurappa on behalf of his party and expressed hope that the new government would ensure cordial ties with Tamil Nadu.

In a Facebook post and a tweet, the leader of the opposition in the state assembly also urged the new dispensation to release soon Tamil Nadu’s share of water from the Cauvery river. “I believe the BJP, which is going to take charge, will not violate Tamil Nadu’s rights on Cauvery as per the Supreme Court order and strive for cordial ties with the neighbouring state," he said.

Tamil Nadu and Karnataka are locked in a decades-old dispute over sharing Cauvery waters. Karnataka had on 3 May said it was not in a position to release Cauvery water to Tamil Nadu even as the Supreme Court sought to know the quantum of water that can be spared.

The Centre had on Monday filed a draft Cauvery management scheme before the Supreme Court, in line with its directive. The apex court on 16 February asked the Centre to formulate the scheme to ensure compliance of its judgement on the Cauvery dispute.

The court had modified the Cauvery Water Disputes Tribunal (CWDT) award of 2007 by raising the 270 tmcft share of Karnataka by 14.75 tmcft and reduced Tamil Nadu’s quantum while compensating it by allowing extraction of 10 tmcft groundwater from the river basin.
