To rally forces against the Indo-US nuclear deal, Bharatiya Janata Party  leader LK Advani on Monday spoke to Communist Party of India (Marxist) leader Prakash Karat and sought his party's vote against the Indo-US deal in Parliament.

"Advani has spoken to Karat. We are in touch with leaders of the Left and the United National Progressive Alliance," party leader and former external affairs minister Yashwant Sinha told mediapersons.

He was replying to a query if the BJP was in touch with other parties opposed to the deal.

"We are in touch with leaders of all political parties (opposed to the deal) for floor coordination," Sinha said. He rejected Prime Minister Manmohan Singh's [Images] statement in Parliament on the deal as a "bundle of same untruths, half-truths and pure white lies".

Advani and other National Democratic Alliance leaders have made a fresh request to Lok Sabha Speaker Somnath Chatterjee to allow a discussion on the deal under Rule 184 that entails a vote. A separate notice has also been sent to the Rajya Sabha secretariat for a similar discussion.
