DMK has called the action against it as a "political vendetta".
"One can understand how the Congress government is working, how are they behaving. This is only political vendetta. Let the CBI do anything, we don't bother. One has to understand how the Congress has stooped down to this level," said DMK MP TR Baalu.
Even Congress leaders like Finance Minister P Chidambaram and Parliamentray Affairs Minister Kamal Nath have opposed the raids. Both the Congress leaders have condemned and disapproved the raids.
"I strongly disapprove of the action by the CBI. It will be misunderstood. It is bound to send a wrong signal. I have spoken to the minister concerned," said Chidambaram.
"However much we condemn it, would be less," Nath said.
Several questions have been raised over the CBI raids on DMK leader, as the raids came just two days after DMK pulled out of Congress-led UPA coalition over the issue of atrocities of Tamils in Sri Lanka.
Opposition BJP has criticised the raids, saying it is the pure misuse of CBI by Congress to settle political scores.
"The BJP has always alleged that the government is misusing the CBI to settle political scores," said senior BJP leader Rajiv Pratap Rudy.
"It is a sharp message to SP and BSP that if they leave the party, they will face the same action. It's indirectly a threat to its remaining allies," he added.
"If any DMK leader has committed graft it must be investigated. But for nine years there has been no raid. Then, why just 48 hours after the DMK pulled out of the UPA government?," asked BJP leader Ravi Shankar Prasad.
"CBI will now dictate everything on Mulayam and Mayawati," added Prasad.
Two days after Dravida Munnetra Kazhagam (DMK) pulled out its support from Congress-led UPA government, the "lame duck" government showed its former ally that it has not become weak after the political "divorce".
In almost as an act of revenge, the Central Bureau of Investigation (CBI) on Thursday, March 21 conducted raids at DMK leader MK Stalin's residence in Chennai.
The CBI conducted raids at the residence of Stalin in connection with a case involving illegal import of foreign cars worth Rs 20 crore. Media reports said that the CBI conducted raids after Directorate of Revenue Intelligence (DRI) complaint regarding case involving alleged illegal import of foreign cars.
