"The yuvraj of Congress ( Rahul Gandhi) is very vocal on the corruption by Mayawati. However, he is not saying anything on the corruption by his own government," Thackeray said in an editorial party mouthpiece 'Samaana'.
"His mummy (Sonia Gandhi) is also quiet on the issue. The Prime Minister is also not opening his mouth. The truth is hidden in the silence," the Sena chief added.
Thackeray said if the Congress really welcomes the Supreme Court decision, then not only Chidambarama but Prime Minister Manmohan Singh should also resign on moral grounds.
"Congress cannot get away by blaming responsibility of the world's biggest scam on a minister," he said.
Referring to a note by Finance Minister Pranab Mukherjee, Thackeray said, "had Chidambaram decided, the scam would have been averted."
"If Chidambaram would have decided, the scam could have been stopped. A letter in this regard was sent by the finance ministry to the Prime Minister, isn't that true?" he asked.
