He was the youngest and the first one of his kind when he was nominated as a principal spokesperson of a political party thirty years back. As a Political Activist, he has seen the inner walls of the prisons quite often. In his fifty-two years of political life, he has participated in many agitations and courted arrest numerous times. He never bothered about pseudo politics and has an impeccable public life. He is soft-spoken and upholds higher ethics in public life. He always fields himself in the domain of trustworthy and genuine political activities.
