The Left continued to reach out to other parties in its bid to topple the UPA Government with CPI General Secretary A B Bardhan meeting RLD chief Ajit Singh in New Delhi on Thursday.

Bardhan drove to Singh's 12 Tughlak Road residence this morning to seek the support of the RLD, which has three members in the Lok Sabha, for the July 22 trust vote and is understood to have explained the Left's position on the nuclear deal and the reason for withdrawing support to the UPA coalition on July 9.

Congress managers have already approached the RLD to ensure numbers on their side for the trial of strength, but Singh is keeping his options close to his chest and has announced that he was not in a hurry to take a decision.

The 59-member-strong Left parties are engaged in an aggressive bid to topple the Government and have already spoken to parties like the BSP, TDP and TRS.

Bardhan had last week set the ball rolling by first talking over phone to BSP chief Mayawati followed by his CPI(M) counterpart Prakash Karat's visit to her residence

A senior CPI leader from Andhra Pradesh opened a channel of communication with the TRS, which announced that it would vote against the Government in the wake of UPA failing to pass a resolution giving a commitment on the issue of formation of a separate 'Telengana'.

Karat had earlier said he was in touch with all parties which can take a stand against the Indo-US nuclear deal, an issue which prompted them to withdraw support to the Congress- led government reducing it to a minority.
