This is the first election for the ruling AINRC that came into power in 2011 assembly election.
Minister of state in PMO V Narayanaswamy, who made his Lok Sabha debut winning the seat as a undivided Congress candidate in 2009, is likely to face a multi-cornered contest, if fielded.
Rangaswamy has not disclosed his poll strategy on whether his party would go it alone or forge a tie up with any political outfit.
PMK, which is likely to strike a poll pact with BJP, has also named its nominee for the coming poll.
M Karunanidhi's DMK and BJP are yet to make known their plans for Puducherry.
Puducherry comprises 30 assembly segments and has a total electorate of 8.85 lakh.
