The Left and other supporting parties will observe a protest day on Wednesday when Prime Minister Manmohan Singh [Images] will meet US president George W Bush [Images] in Washington to "formalise" the 123 Agreement.

The CPI(M), CPI, RSP, Forward Bloc, TDP and JD(S) will hold two protests in the national capital -- one at Parliament House and the other at Jantar Mantar -- to highlight its objection to the agreement which they claimed will compromise India's sovereignty and vital interests.

"The prime minister has gone back on his assurance that he will come back to Parliament after getting the clearance from the IAEA and the Nuclear Suppliers Group.

"Parliament has been convened only on October 17, well after the nuclear deal will be sealed in Washington," the parties said. Besides rallies and demonstrations across the country, the MPs of these parties would also hold a mass dharna in the Parliament House premises against "the gross contempt and violation of parliamentary democracy."

"The refusal to call Parliament comes at a time when the country has suffered a series of terrorist blasts, attacks on Christian minorities, continuing price rise and adverse impact of the US financial crisis," the parties said.

They said the protest day was being planned against "the signing of the nuclear deal and the bypassing of Parliament".

The protest actions would be held across the country against "this surrender to the United States".

Interestingly, the Bahujan Samaj Party, which also came together on a joint platform with all these parties last month, is not among the signatories to the joint statement.
