A day after she had made a veiled attack on the Left parties on the Indo-US nuclear deal, CPI(M) leaders Prakash Karat and Sitaram Yechury on Monday met Congress president Sonia Gandhi.

The 30-minute meeting came on the eve of the next round of discussions of the UPA-Left committee set up to address the Left parties' concerns over the deal.

Senior Congress leaders and Union Ministers Pranab Mukherjee and A K Antony as also political secretary to AICC president Ahmed Patel also joined the meeting at Sonia's residence this evening.

The Left parties have reacted to Sonia's remarks at the public meeting in Jhajjar by saying that the UPA has surrendered the country's vital interests to America on the agreement.
