The heat over the Indo-US civilian nuclear deal looked set to be lowered, at least for now, with the Left veering around to accepting the UPA’s offer for a “political mechanism” to look into their objections to the Hyde Act even as the government remained non-committal on the Left’s demand to press the “pause” button on any further negotiations on the deal.

The details of this political mechanism — its duration and its terms of reference — agreed upon by the CPI and the CPM today, will be finalized after Congress negotiators conclude talks with the two other Left parties Forward Bloc and RSP. Before giving the final OK, the Left parties will also discuss it among themselves.

Those involved in negotiations said that the mechanism could take the form of a UPA-Left “political committee” headed by troubleshooter External Affairs Minister Pranab Mukherjee and experts could be roped in for their inputs. Sources said its timeframe was likely to provide at least a month-long breather to both sides. “We reiterated our position to the government in this first round of talks. We are expecting something concrete by this month end,” said CPM Politburo member Sitaram Yechury who, along with party general secretary Prakash Karat, had an hour-long meeting with Mukherjee, Ahmad Patel, political secretary to Congress president Sonia Gandhi and Defence Minister A K Antony this evening.
