Tamil Nadu finance minister D Jayakumar, however, said there were "contradictions" in the rival camp, with each leader making different statements.
Mr Jayakumar pointed out that Mr Panneerselvam had said "conducive atmosphere" prevailed for the merger talks, but others, including former ministers S Semmalai and K Pandiarajan, were making different statements.
"... (there are) contradictions among themselves. Our only stand is let's talk," he told reporters in Chennai.
"We are clear. Come, sit, talk. We are openly saying that let us settle whatever the disputes be," he added.
Sticking to their stand for commencement of merger talks, Mr Panneerselvam aide and Rajya Sabha member V Maithreyan had reiterated the AIADMK (Puratchi Thalaivi Amma) faction's demand for the state government recommending a CBI probe into J Jayalalithaa's death besides removal of party chief VK Sasikala, her deputy TTV Dhinakaran and members of her family from the party.
"Only if these demands are met, the talks will happen. We are clear on that," he had said.
