The Chief Minister, Mr A.K. Antony, has said that the Kerala State Government has informed the national taskforce on interlinking of rivers, headed by Dr Suresh Prabhu, that the proposal to link two of its rivers, Pampa and Achenkoil, with Vaippar in Tamil Nadu was not acceptable to it. Answering a question in the State Assembly on the first day of the monsoon session here on Monday, the Chief Minister said the State Government's unflinching stand was made clear in response to a letter from the Chairman of the task force officially seeking the Government's view on the proposal.
