Disclosing this, TN public works minister Durai Murugan told reporters here today that the assurance was given when Karunanidhi contacted Naidu over telephone last night.

He said the AP irrigation minister Thummal Nageswara Rao, whom he had contacted last night, told him that there would not be any problem in releasing water from the reservoir. The AP minister told him that the Congress volunteers in Nellore district had been demonstrating against the release of water only with an eye on the coming Lok Sabha elections, Durai Murugan said.
