Which of the given leader is not the founding Member of NAM?

Indira Gandhi

The correct answer is option (3) - Indira Gandhi

Indira Gandhi was not a founding member of NAM.

The roots of NAM went back to the friendship between three leaders — Yugoslavia’s Josip Broz Tito, India’s Jawaharlal Nehru, and Egypt’s leader Gamal Abdel Nasser — who held a meeting in 1956. Indonesia’s Sukarno and Ghana’s Kwame Nkrumah strongly supported them. These five leaders came to be known as the five founders of NAM. The first non-aligned summit was held in Belgrade in 1961.
