Criticising Congress president Sonia Gandhi for being “quiet” on the 2G spectrum scam, Shiv Sena supremo Bal Thackeray on Friday hit out at Home Minister P Chidambaram, saying he should resign immediately.

“The ‘Yuvraj’ of Congress (Rahul Gandhi) is very vocal over the corruption by Mayawati. However, he is not saying anything about the corruption by his own government,” Mr. Thackeray said in an editorial in party mouthpiece Saamana.

“His mother (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.

Mr. Thackeray said if the Congress indeed welcomes the Supreme Court decision, then Mr. Chidambaram and Prime Minister Manmohan Singh should resign on moral grounds.

“Congress cannot get away by placing responsibility of the world’s biggest scam on a minister (A Raja),” he said.

Referring to Finance Minister Pranab Mukherjee’s note, Mr. Thackeray said the scam could have been averted if the then Finance Ministry had insisted on the auction route.

“If Chidambaram would have decided (about the auction route of spectrum), 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.
