"I condemn this strongly and deny such reports completely. Somebody has spread such rumours with malicious intent," he told reporters.
"I would like to state categorically that this has been done deliberately to create confusion among party ranks," he added.
He was referring to reports that he had offered to quit as DMK treasurer as his father and party chief M Karunanidhi did not allow him to contest for the post of General Secretary.
DMK is in the last phase of concluding its organisational polls. Elections for the top posts of party president, General Secretary, treasurer and audit members will be held on January 9.
Stalin said that nomination papers for contesting the post of party treasurer will be filed on January 7.
"The truth is that our leader Karunanidhi and K Anbazhagan (former Finance Minister) will file papers for the posts of party president and General Secretary," he said.
