New Delhi: The Cauvery river water issue was raised by the Dravida Munnetra Kazhagam (DMK) on Thursday as soon as President Ram Nath Kovind began his address to the joint sitting of both houses of Parliament.

DMK members held placards and briefly raised slogans on the issue of distribution of Cauvery water between Karnataka and Tamil Nadu.

Vice president M Venkaiah Naidu was seen trying to pacify them and convincing them to sit down.

During the President's address several National Democratic Alliance (NDA) MPs thumped desks when Kovind referred to the Modi government's philosophy of 'Sabka Sath, Sabka Vikas aur Sabka Vishvas'.

When the President referred to the Rafale jet deal and the delivery schedule of the Apache attack helicopters, defence minister Rajnath Singh was seen smiling and thumping the desk along with other NDA members.

As soon as the speech got over, Kovind walked up to the first row where Prime Minister Narendra Modi, Union Ministers and floor leaders of parties were sitting.

He shook hands with all of them including Rahul Gandhi.

Kovind was accompanied by Naidu.
