TRS MP and daughter of Chief Minister K Chandrasekhar Rao claimed that 80 per cent of the candidates supported by the ruling party had won in the polls.
"Sarpanch elections were held in three phases. If you observe the results, over 80 per cent of the total candidates won are supporters of TRS. By default there were some wins for supporters of other parties.
