"I will never fall as the Congress party and the people's thirst for freedom are behind me. It is going to be a continuous fight," he told reporters in Chennai.
Mr Chidambaram also accused the government of trying to wreck his physical health, adding they succeeded for about 10 days.
"After the court's intervention and examination by doctors, my health has more or less improved fully," he said.
Speaking on economy, Mr Chidambaram claimed that it was moving towards the worst phase and cautioned the people to be on guard.
"I will continuously speak and write," he said.

Mr Chidambaram said that the entire country is turning into a killing field for the women, especially Uttar Pradesh. He added that the responsibility of women's safety lies not only with the governmenr but also man "Every man should protect women," he said.
