The ruling AIADMK in Tamil Nadu and the BJP on Tuesday sealed an alliance for the coming Lok Sabha elections, under which the saffron party would contest five seats in the state.

The announcement was made by AIADMK coordinator and deputy chief minister O. Panneerselvam and Union minister Piyush Goyal, the BJP election in-charge for Tamil Nadu. Goyal described it as a 'mega alliance'.

The announcement came after the second and final round of discussions held in Chennai by the two parties that also involved chief minister K. Palaniswami.

Earlier in the day, the AIADMK clinched a deal with the PMK, offering the Vanniyar-based party seven out of 40 seats, including one in the neighbouring Union Territory of Puducherry.

It is not clear yet how many seats the AIADMK will contest.
