Chennai: In the war for the election symbol ahead of the Tamil Nadu by-polls, the Election Commission of Thursday allotted the party name 'AIADMK Amma' for VK Sasikala's faction and 'AIAMDK Puratchi Thalaivi Amma' for O Panneerselvam's faction.

As the parties were not allowed to use the original 'two leaves' symbol, EC gave 'Hat' symbol to Sasikala's team and 'Electricity Poll' symbol to the OPS camp.

Earlier, the Election Commission in an interim order late Wednesday night had frozen the 'two leaves' poll symbol AIADMK and also decided that neither of the two factions will use the party's name.

After hearing through the day arguments of contending factions -- one led by General Secretary V.K. Sasikala and another led by former Chief Minister O. Panneerselvam -- the poll panel decided that neither of the two groups will be permitted to use the 'two leaves' symbol and use the name All India Anna Dravida Munnetra Kazhagam (AIADMK).

The panel said both groups shall be known by such names as they may choose showing, if they so desire, linkage with their parent party -- AIADMK.

Both the groups shall be allotted different symbols from a list of free symbols notified by the EC for the purposes of the current by-election from Radhakrishnan Nagar assembly constituency in Tamil Nadu.
