DMK general secretary Duraimurugan on late Saturday evening suspended Sivaji Krishnamurthy, one of the party's headquarters speakers from Chennai, against whom Raj Bhavan had lodged a police complaint late on Friday night.
Governor R N Ravi's Deputy Secretary had filed a complaint with Chennai Police Commissioner Shankar Jiwal accusing Sivaji of making derogatory remarks against the Governor and also speaking in an intimidating tone.
At a party public meeting Sivaji, known for making double meaning comments - as is the case with most platform speakers of political parties - admonished the Governor for not reading out the address prepared by the Government on the opening day of the recent Assembly session.

Separately the State BJP addressed a complaint to the DGP seeking action against Sivaji.
Following an unprecedented faceoff with the Governor in the Assembly on Monday, Chief Minister M K Stalin had told his party legislators that the Government had given a befitting and appropriate response to Ravi and urged them not to speak ill of him in other forums.
Though initially the DMK leadership appeared disinclined to act against Sivaji, the complaint from Raj Bhavan, which is a rare occurrence, made it difficult for the ruling party and it chose to suspend him.
Earlier in the day, in a fleeting remark at a party meet, Stalin without naming the Governor, said there is a person who is ranting against the State being called Tamil Nadu.
What Krishnamoorthy said against TN Governor
"In Tamil Nadu, if this man refuses to utter the name of Ambedkar, my forefather who gave the constitution to India, do I have the right to hit him with a slipper or not? Didn't you take an oath in the name of the constitution?
"Wasn't it Ambedkar, my grandfather, who wrote it? If you won't say his name, you go to Kashmir. We ourselves will send an extremist. Let him gun him down," Shivaji Krishnamoorthy, DMK platform speaker, said.
The DMK has distanced itself from the remarks, saying the party respects the Governor and the hateful remarks were an individual's personal speech.
