New Delhi, Feb 9 (IANS): Tamil Nadu Chief Minister M. Karunanidhi would be jailed soon for his involvement in the 2G spectrum scam, Janata Party president Subramanian Swamy said Wednesday.

"Karunanidhi and Raja are equally involved in the telecom scam. We are starting a kind of revolution in Tamil Nadu demanding stringent punishment for the culprits and you will see the results soon," Swamy said during an interaction with Delhi University students.

The session, titled 'The significance of fighting against corruption', was organised by the Delhi University Students' Union (DUSU) and the NGO Sahbhag at the Faculty of Arts in the north campus.

The former union minister said DMK chief Karunanidhi and party MP Raja had got the backing of Congress president Sonia Gandhi and the money divided between the three.

"These are the big fish in the case and I have filed a case against Karunanidhi who would be in jail soon," said Swamy, adding that Prime Minister Manmohan Singh was a mute spectator.

"I am not questioning his integrity but it is a fact that when the country is being robbed by criminals from every corner, our PM is silent and it seems is not interested in punishing the guilty," Swamy said.

It was Swamy's public interest litigation in the Supreme Court, filed in his personal capacity, that brought the 2G spectrum allocation auction to the political centrestage.

Raja resigned as telecom minister Nov 14 after the Comptroller and Auditor General (CAG) reported that the faulty auction process in the allocation of second-generation telephony had led to a notional loss of Rs.1.76 lakh crore.

He is in the custody of the Central Bureau of Investigation (CBI) for his alleged role in the scam, billed as the country's biggest corruption scandal to date.
