P. Santhanakrishnan is a political figure from Tamil Nadu associated with the All India Anna Dravida Munnetra Kazhagam, known for his role within the party organisation. He has been identified as a senior functionary within AIADMK’s Chennai political structure.
In the 2026 Assembly elections, he was selected as the AIADMK candidate for the Kolathur constituency, a key urban seat in Chennai.
His candidature is strategically significant as Kolathur is represented by Chief Minister M. K. Stalin, making the contest one of the most high-profile direct battles between the ruling DMK and the opposition AIADMK.
His political profile is therefore defined by his organisational role within the party and his selection to contest in a high-stakes constituency rather than a long record of electoral victories.
In the 2026 Tamil Nadu Assembly election, P. Santhanakrishnan contested as the AIADMK candidate and lost after polling 18,430 votes. He was defeated by TVK candidate V. S. Babu, who secured victory by a margin of 64,567 votes.
