The woman, who filed a sexual abuse case against Binoy Kodiyeri, son of Kodiyeri Balakrishnan who is the state secretary of CPM's Kerala unit, said that she has evidence against him and would fight the case.
"I stand by the charges I have made. I am ready to submit the evidence too. I will fight the case legally," the woman, who was a bar dancer, told Manorama News on Tuesday.
"I gave the complaint knowing fully well that he is a powerful person in the society," she said.
CPM politburo member Brinda Karat has said that the party would not protect anyone.
"As it is a case against an individual, there is nothing the party can do in this. It is for the individual to prove the allegations wrong," Brinda Karat said in Delhi.
CPM national general secretary Sitaram Yechury said that he was not aware of the complaint against Binoy.
The central leadership was of the opinion that there was no need to intervene in the issue now.
The sexual abuse allegations against the son of the party secretary has put the CPM in a fix in Kerala.
The Mumbai police registered a case of rape and cheating against Binoy.
The case was filed on the basis of a complaint from a 33-year-old woman from Bihar, who has alleged that Binoy sexually assaulted her promising marriage and that she has an eight-year-old son from him.
Admitting that he knew the woman, Binoy, however, said the allegation was "baseless".
Six months ago, the woman had sent a letter to him demanding Rs five crore and alleging that he had married her and had a child from her, Binoy told television channels in Thiruvananthapuram.
Binoy said the Mumbai police had not got in touch with him so far and that he was prepared to face the case legally.
The woman also claimed that she came to know last year that the accused was already married, following which their relationship turned sour.
She also alleged that the accused threatened her with dire consequences.
