Her decision came following an invite from the CPI(M) state secretary Kodiyeri Balakrishnan to return to the party- fold.
Balakrishnan told PTI that Gowri Amma, who founded a political party Janathipathiya Samrakshana Samithy (JSS) after she was expelled from CPI(M) in 1994 on charges of anti-party activities, would work with the party.
"A rally will be organised on August 19--the martyrdom day of P Krishna Pillai--founder of the Communist movement in Kerala--in Alappuzha in which she will announce her decision to work with CPI(M)," Balakrishnan said after his talks with Gowri Amma at her residence here.
Gowri Amma, a prominent figure in the Communist movement in Kerala, and her party had been associated with CPI(M)- led LDF after severing her ties with UDF following her party's defeat in the assembly polls in 2011.
She was a minister in the first Communist government in Kerala headed by E M S Namboothirippad in 1957.
