1)The spoke person Mr. Manish Tiwari who quoted " Hazare is totally corrupt person" is elevated as Minister. 2) Whole world knows Chidambaram earned lot of money in 2G spectrum deal is entrusted as Finance Minister. 3) Mr. Salman Khursheed is actively involved in scam of funds made available by Ministry of Social Justice. He, who is Law Minister of India caught saying that " Hum khoon se likenge" is elevated as External affairs Minister ...... AND Mr Jaipal Reddy has been shifted from Petrolium Ministry. Do you think Mr. Manmohansingh can claim that he is non corrupt PM? Define Non corrup
He may not be indulging in corruption and making money himself but his silence and paying Nelson's eye to wrong things going on around specially by some Ministers shows that he is indirectly to be blamed for what you have mentioned about the above ministers.
Only those who personally indulge in corruption are not to be blamed. Those who know who are indulging in corruption and do not act against such persons are also sharing the blame.

It is just possible that MMS is being used by corrupt politicians. Once in, he can not come out easily. He has no guts to stand up to injustice and speak out the truth. He has to save his chair, and it seems, he is ready to go to any length for that.
