As a consequence, he said the attacks on CPI(M) were being stepped up "as the prospects of the deal being operationalised as per the American deadline fade away".
"A desperate attempt is being made to urge the government to go ahead with the nuclear deal ignoring the objections of Left parties and the entire opposition," Karat said in an article in the party organ "People's Democracy".
"One of the worn out charges resurrected" to discredit the CPI(M) stand and to favour the deal going ahead was the accusation that the major Left party, "the third largest in Parliament", was "acting at the behest of China", he said.
In the article titled "Nepal: Portents for South Asia", Karat said the US, as part of its "hegemonic designs", had planned to "wreck" the political process in the Himalayan nation to make it a democratic republic.
