AMMK leader TTV Dhinakran on Tuesday launched a scathing attack on the AIADMK leadership, saying the ruling party has "lost its identity" and was "stuck" due to a "few selfish" people.
The ousted AIADMK leader also claimed that his Amma Makkal Munnetra Kazhagam (AMMK) would 'retrieve' the ruling party.
"One cannot deny the fact that the party has lost its identity and ideology and veered away from the path laid down by Amma (the late J Jayalalithaa). It is now stuck due to a few selfish persons," he alleged without naming anyone.
He was apparently targeting AIADMK Coordinator O Panneerselavam and the Joint Coordinator K Palaniswami, with whom he is in a running feud for control of the ruling party.
Mr Palaniswami is Chief Minister of Tamil Nadu while Panneerselvam is his deputy.
In a letter to partymen ahead of the AIADMK founding day on October 17, Dhinakaran said while the late Chief Minister M G Ramachandran had launched it, Jayalalithaa had taken it forward and made it a popular movement in the state.
But post her death in 2016, "dominant forces" had taken over the party, he said in the letter.
Reiterating his oft repeated charge of the AIADMK being 'subservient' to the BJP-led government at the Centre, he said his AMMK would retrieve the AIADMK and restore it to its old pride.
The AIADMK has "lost its identity and become someone's slave," he said but did not name anyone.
Mr Dhinakaran claimed 90 percent of AIADMK workers were supporting AMMK and that the rest were in the ruling party due to "selfish motives."
"AMMK has been the true AIADMK. In the coming days, it will retrieve AIADMK," he added.
His victory in the RK Nagar bypoll in December 2017 was proof of people's sentiments as the voters elected him as Jayalalithaa's successor, he said.
The bypoll was necessitated due to the death of Jayalalithaa in December 2016. Mr Dhinakaran, who contested as an Independent, had defeated ruling party nominee E Madhusudhanan by a good margin.
Earlier, Mr Paneerselvam had in February 2017 fallen out of favour with then AIADMK interim general secretary V K Sasikala and resigned as the chief minister.
Mr Palaniswami was subsequently made his successor by Sasikala, who also appointed Dhinakaran as AIADMK deputy general secretary, before leaving for Bengaluru to serve a four-year jail term in a disproportionate assets case.
