"I am not keen to contest the elections due to health reasons and cinema commitments," she told reporters at Wadakancherry, the constituency from she was expected to contest the May 16 polls.
She insisted, however, that she was not withdrawing due to the protests by some party workers. She added that she has already informed the party about her decision.
Yesterday, Democratic Youth Federation of India (DYFI) activists had taken out a protest march in Wadakancherry against the CPI-M's proposed move to field the 69-year-old actress. Earlier, posters appeared in various parts of the constituency against her candidature.
"We will only be too happy to put her up as our candidate. Candidates like Lalitha will help improve the party's image," he said.
