Modi took to Twitter to express that she was a central figure of the Indian National Congress. She was the first and, to date, only female Prime Minister of India.
"Tributes to our former PM Smt. Indira Gandhiji on her death anniversary," the Prime Minister said.
The Prime Minister had paid tribute to Gandhi in his monthly Mann ki Baat radio broadcast last Sunday as well.
Born on November 19, 1917, in Uttar Pradesh's Prayagraj, Gandhi was assassinated by her own bodyguards on October 31, 1984, here following the Operation Blue Star.
