Jayalalithaa said she was happy to announce that the AIADMK and the CPI had decided to enter into an alliance to fight the polls.
"Other details will be worked out later," she added.
She said the present aim was to win all the 40 Lok Sabha seats -- 39 in Tamil Nadu and one in Puducherry.
She said the election plank would be peace, prosperity and progress.
According to Bardhan, the prospects of Jayalalithaa becoming prime minister could open up if the AIADMK-Left alliance won the elections.
