Do the congress member in PAC attempt to weed out Dr MM Joshi, clearly pointing towards corruption in PMO?

While the draft PAC report only confirms. only routine official procedure of the Indian Government that any such controversial deal what leads a Telecom Minister Mr A Raja to Tihar Jail, obviously the records must be rooted through PM and Finance Minister and the same has been drafted in the committee's report alongwith provable documents. In such cases, both PMO as well as FM, say they do not know the issue then it reflects their ignorance which is a summonised offence and if they know the issue then why they have not done anything to stop such illegality which is also an offence liable to summon to PAC. Then, where is the mistake that Mr. Joshi, committed as a role of his Chairman,PAC. In such case, removing him as Chairman,PAC and appointing another man by mere 11 members of PAC speaks not only about crossing their limit beyond the Speaker, LS, the appointing authority of the Chairman,PAC, but also confirms the illegality in both PMO as well as FM in encouraging such huge corruption by Telecom Minister just down one layer of PM
