Ahead of the UPA-Left committee meeting, External Affairs Minister Pranab Mukherjee and RJD chief Lalu Prasad on Wednesday met Prime Minister Manmohan Singh and are understood to have discussed a formula to resolve the deadlock over the Indo-US nuclear deal issue.
Mukherjee and Prasad drove to Singh's residence about an hour before the UPA-Left meeting and were there for over 45-minutes.
During the meeting, a formula aimed at ending the deadlock over the nuclear deal is understood to have been discussed.
The formula is believed to be aimed at suggesting ways to placate the Left parties, which are opposed to the deal, so that the government could survive.
Soon after meeting with the Prime Minister, Mukherjee and Prasad headed straight for the meeting of the UPA-Left committee at the External Affairs Minister's residence during which the formula would be considered.
It was the second meeting that Mukherjee had with the Prime Minister during the day.
While Mukherjee and Prasad were meeting the Prime Minister, leaders of the Left parties went into a huddle to devise their common strategy to be adopted at the UPA-Left meeting.
The meeting was attended by CPI(M) General Secretary Prakash Karat, CPI's AB Bardhan, D Raja and TJ Chandrachud and Debabrata Biswas and G Devarajan from Forward Bloc.
After the deliberations, sources indicated that today's UPA-Left meeting could be the last as the Left parties had decided to make it clear to the government that they had said what they had to and it was for the government to take a call.
The Left parties have already rejected a compromise formula which would have allowed the government to finalise the safeguards agreement at the IAEA.
Earlier in the day, Karat held talks with Mukherjee over the issue following which the CPI(M) leader met Samajwadi Party chief Mulayam Singh Yadav.
