UPA will give priority to Cauvery issue, if voted to power: PM

"Cauvery is a sensitive issue. Efforts have been made (to resolve the dispute)," he said at a press conference here.

The Prime Minister said a permanent solution has to be found out to the problem, which involves Tamil Nadu, Karnataka, Kerala and Puducherry.

"If we come back to power, we will give it a priority," he said.

The sharing of Cauvery water among the riparian states remains a ticklish issue during the summer months with Tamil Nadu demanding its share of water from Karnataka.
