"Victory for #OPS dharma yuddham ! All 3 key demands by OPS met decisively! Time to transparently negotiate for merger! #UnitedAdmk," former minister and a leader of Panneerselvam faction Mafoi K Pandiarajan tweeted.
However, another senior leader of the camp appeared guarded in his reaction, saying they had demanded a CBI inquiry into Jayalalithaa's death.
It was, however, the chief minister's view to have a Commission of Inquiry instead, former minister K P Munusamy said.
Pandiarajan said he was delighted to welcome the announcement made by Chief Minister K Palaniswami on the probe and that it was time to negotiate in a transparent manner for merger of the factions.
"Delighted to welcome 2 key moves by #EPS (Edappadi K Palaniswami) to set up judicial enquiry into Amma's expiry & to convert Veda Nilayam into Memorial! #UnitedADMK," he said in another tweet.
