Anti-nuclear activist S P Udayakumar with his around 500 supporters today joined Aam Aadmi Party in Tamil Nadu ahead of Lok Sabha polls.
"We have formally joined the AAP today," 'People's Movement Against Nuclear Energy' convener Udayakumar here said.
The PMANE spearheads the more than two-year old protest against the Kundakulam Nuclear Power Plant in district Tirunelveli.
An announcement on the names of candidates contesting the polls from southern districts would be made public soon by AAP's top leadership, he told PTI.
Asked if he would continue to be associated with PMANE, Udayakumar, against whom several cases had been registered in connection with the anti-KNPP protests, said "Of course yes..I continue to be an anti-nuclear activist."
Besides Udayakumar, M P Jesurajan and Peter Milton were among the other prominent anti-nuclear activists who joined the party.
However, Pushparayan and Mugilan, two other PMANE leaders, did not join the party.
"They do not believe in party politics, they have right to their opinion and we did not force them either," Udayakumar said.
AAP leader Prashant Bhushan had met Udayakumar recently, triggering reports about the party roping in the activist.
