Even though contestants of four major political forces are in the fray for the April 23 polls, Alangulam, which elected former Assembly Speaker S. Chellapandian, is witnessing a keen tussle between the candidates of the ruling DMK and the AIADMK as sitting MLA takes on a former MP.

After winning the first Assembly election in Alangulam constituency in 1952, the Congress lost this segment to an independent candidate in the next election and retained it in 1962. S. Chellapandian won the election to become the Speaker when K. Kamaraj was the Chief Minister.
