However, the AAP is yet to make an official announcement regarding his candidature, and he is likely to contest from Kanyakumari, Tirunelveli or Tuticorin constituency.
According to a news report, Udayakumar said that he agreed to contest polls after AAP made its nuclear policy clear to him.
Tamil Nadu unit of the AAP will be called 'Common People's Party'
He also said that the Tamil Nadu unit of the AAP will be called "Eliya Makkal Kachchi" which means 'Common People's Party'.
A known opponent of the Kudankulam Nuclear Power Plant (KNPP) in Tamil Nadu, Udayakumar movement against the nuclear plant has been joined by Arvind Kejriwal and Prashant Bhushan, in the past.
Prashant Bhushan's visit to Idinthakarai to meet Udayakumar, last month, had also sparked off speculation that the party could pull the anti-nuclear campaigner into its fold.
Bhushan aslo showered praise on him saying, "Udayakumar is an outstanding, courageous activist and a honest man and the AAP welcomes him with open arms".
