"I demand that Congress party should immediately start a discussion on Rafale," Jaitley said.

The Bharatiya Janata Party members were on their feet asking Congress President Rahul Gandhi to apologise.

"Rahul Gandhi maafi maango (apologise)," the ruling party MPs said in a chorus.

This came after the Supreme Court on Friday dismissed petitions demanding court-monitored probe into the Rafael fighter jet deal.

Earlier, as soon as the House met for the day, some members belonging to the DMK and AIADMK trooped to the Chair's podium, holding placards.

They have been protesting against a proposed dam over the Cauveri river.

Amid the pandemonium, Deputy Chairman Harivansh adjourned the House for 20 minutes.

But as the House was reconvened at 11.30 a.m., the scene was no different. He tried to go ahead with the Zero Hour but nothing could be heard over the din.

The Chair then adjourned the House for the day.
