Pushpa was expelled from the AIADMK back but she did not resign from the upper house.
The general council meeting of the AIADMK is slated to be held on Thursday. Pushpa had announced that she would contest for the party�s top post of general secretary which fell vacant following the death of former chief minister J Jayalalithaa.
Several party officials had pleaded with Jayalalithaa�s close aide VK Sasikala to take over as the party�s general secretary, which was opposed by Pushpa.
Policemen were deployed outside the AIADMK office on Wednesday morning, anticipating the arrival of Pushpa to get the form to contest for the top party post.
However, her supporters and lawyers turned up at the party office shouting slogans and angering the party cadres which in turn resulted in a clash.
The police escorted one person with a bloodied face.
