The PMK on Tuesday announced its decision to go it alone in the Assembly polls in Puducherry scheduled to be held on April 6. The announcement comes a day after the S Ramadoss led party commenced parleys with the BJP on the number of seats to be contested as part of the NDA, which remained inconclusive. Convenor of the Puducherry unit of PMK K Dhanaraju told PTI that his party was kept in dark on the seat sharing exercise between the AINRC, AIADMK and BJP and the decision these parties had taken on sharing of seats. I had presented a letter to the BJP observer for Puducherry, Nirmal Kumar Surana at a meeting here on Monday, seeking allocation of five seats for the PMK to contest the forthcoming election as part of NDA.
