"The track record of TMC has been such that they say something and do another thing. So till something happens tangibly, we won't be able to decide," CPI(M) politburo member and MP Sitaram Yechury told reporters here.
"If something like that happens then we will see at that stage. But we never know what will finally happen," Yechury said responding to a question on TMC chief Mamata Banerjee's appeal to UPA allies and Left parties for support to her party's no confidence motion in Parliament.
Yechury also said "If you are bringing a no confidence motion .. If you are not successful, then that becomes a licence for the rest of the tenure of the government to say that Parliament has endorsed all that we are doing .. Now that sort of a clean certificate we don't want to give."
The CPI(M) has already given notice for division of votes on FDI in retail sector issue. "We want the opinion of the House before the government goes ahead on implementing it (FDI in retail)," the CPI(M) leader said.
Asked whether his party would go along with the BJP on the FDI issue, Yechury said: "Let them come."
Replying to a question on the possibility of early polls, the CPI-M politburo member said, "only two parties - SP and BSP- can give a reply to that. The UPA government has no majority in the Lok Sabha".
"They survive on outside support from SP and BSP. They can only say how long the government will last," Yechury said.
