Najma Heptullah, a former Congress leader who joined the BJP almost a decade ago following reported differences with Congress president Sonia Gandhi, is the grand-niece of Maulana Abul Kalam Azad, freedom fighter and a minister in the first Indian government after independence.
Heptullah, 74, held several important positions in the Congress before switching ranks.
She was a general secretary of the party and served for four terms in the Rajya Sabha from Maharashtra.
She also served twice as deputy chairperson of the Rajya Sabha.
In 2004, Heptullah in an interview to a TV channel accused Congress president Sonia Gandhi of "humiliating" her. She claimed that the Congress leadership of the time had moved away from the ideals of its former leaders like Jawaharlal Nehru, Sardar Patel and her grandfather Maulana Abul Kalam Azad.
