Rubbishing the draft report of the Joint Parliamentary Committee (JPC) on 2G scam as a “dubious report” senior MP of the Communist Party of India Gurudas Dasgupta accused Prime Minister Manmohan Singh here on Saturday of “dereliction of duty”, alleging that he (the PM) was fully aware of irregularities in dispensing of telecom licences.

Mr Dasgupta called for rejection of the report saying that he will speak in this regard to Trinamool Congress Chief Mamata Banerjee on Sunday.

Citing several letters written by Cabinet Ministers and notes from senior bureaucrats including Cabinet Secretary who have raised concerns over the allotment of licences, Mr Dasgupta also a member of the JPC, said that it has been proved beyond doubt that Dr Singh did not listen to anyone including his own Cabinet colleagues in the matter.

Appealing to all the members of the JPC to defeat the ``resolution”, he said that he was “planning to prepare and present a parallel report” as “this wrong cannot be accepted”.

Criticising the JPC chairperson -- Congress MP P.C. Chacko for behaving more like a Congressman and less like a chairman of the JPC, Mr Dasgupta said that the "report was not leaked but handed over to the media".

“Our only target is to defeat the report and expose the bankruptcy of the Congress party,” he said adding that he is ready to talk to all political parties like the Bharatiya Janata Party and Trinamool Congress over the matter.

“Tomorrow I will try to seek the support of Mamata on this issue,” Mr Dasgupta said.

Stating that Dr Singh was all aware of the irregularities, the MP pointed out that in a letter in November 2007 Kamal Nath had advised the Prime Minister on setting up of a Group of Ministers for allocation of spectrum. Mr Dasgupta also referred to note from then Cabinet Secretary, stating the value of licences of spectrum should be increased.

“ He ( Dr Singh) must have believed that any pre-emptive measure would have rocked his boat and his government would have fallen,” he said.

Referring to the JPC report in the Harshad Mehta scam in 1992, Mr Dasgupta who was also a member of committee then, said that while Mr Mehta and also the then Finance Minister Dr Singh had deposed before the parliamentary committee the JPC probing 2G scam did not take any such steps.
