The Left parties led by the Communist Party of India-Marxist and the CPI are spearheading the no trust vote to topple the United Progressive Alliance government on July 22 when the motion will be put to vote.

Raja added that the Congress party did not adhere to the CMP that was agreed when the Left decided to support the UPA government from outside when not a single party could get the required simple majority to form the government in May 2004.

"We are also not happy that they could not control inflation," Raja said. He also blamed the Congress party for not doing anything for the unorganised work force.

"We have been harping on it for four years. We are not satisfied with the implementation of the National Rural Employment Guarantee Scheme. So these are our differences. If you call that being upset, then so be it. It's not personal. We have nothing against anybody personally. We have policy differences."

About the Left joining hands with Bahujan Samaj Party leader Mayawati, Raja said, "She has also been opposing the policies of the central government. She too opposes the nuclear deal. We both oppose the deal. So we are with her on this issue. There is no other issue right now. After the trust vote we will discuss further action."
