Jayalalithaa said in a statement that Vaigaiselvan, also a former minister, was being fielded in place of M G Muthuraja whom she had announced as candidate for Aruppukottai while releasing her party's candidate list yesterday.
She did not assign any reason for the change.
Vaigaiselvan, a fine orator, wasSchool Education Minister in the Jayalalithaa cabinet but was removed by her later.
