The United Progressive Alliance-Left Committee is expected to come out with its findings on the Indo-US nuclear deal after Diwali, Communist Party of India-Marxist politburo member Sitaram Yechury said in Bangalore on Sunday.

However, Yechury made it clear that consensus on the issue was not possible unless the Left parties' concerns were met.

"May be after Diwali... sometime," Yechury told reporters when asked when the committee was expected to come out with its report.

He also said that the meeting of the committee slated for Monday will not be the last one.

"Tomorrow's meeting may not be the last meeting. There may be more meetings in the future. Till the meetings are over and till our concerns are taken on board, we expect the government not to proceed (in operationalising the deal)," he said.

The CPI-M leader said the Left parties are attending Monday's meeting with the understanding that the findings of the committee will be taken into account before the government proceeds to operationalise the 123 agreement.

According to him, the Left parties expect the government to respond to issues raised by them regarding impact of the deal on India's foreign policy and security concerns, at the meeting.

"In tomorrow's meeting, we will know how the government wishes to proceed and on that basis, we will take our future decisions," Yechury said.
