Former External Affairs Minister and senior BJP leader Sushma Swaraj was cremated on Wednesday with full honours at the Lodhi Road crematorium in Delhi.
Hundreds of people, including Prime Minister Narendra Modi, BJP president Amit Shah and veteran party leader L K Advani paid their last respects.
Bhutan's Prime Minister Tshering Tobgay, several leaders from the NDA as well the opposition, were also present.
Swaraj passed away on Tuesday night after suffering a cardiac arrest.

"A glorious chapter in Indian politics comes to an end. India grieves the demise of a remarkable leader who devoted her life to public service and bettering lives of the poor. Sushma Swaraj ji was one of her kind, who was a source of inspiration for crores of people," Prime Minister Narendra Modi said in a series of tweets.
Several senior ministers, including Harsh Vardhan, Rajnath Singh, Smriti Irani Prakash Javadekar, reached AIIMS after she was admitted to the hospital.
Swaraj had put out a tweet in the evening congratulating Prime Modi after the Centre's move to revoke special status for Jammu and Kashmir and bifurcate the border state into two Union Territories secured Parliament's approval.
"Narendra Modi ji - Thank you Prime Minister. Thank you very much. I was waiting to see this day in my lifetime," she had said.
Prime Minister Modi, in his tweets, hailed Swaraj as a "prolific orator and outstanding parliamentarian" and said she was admired and revered across party lines.
"She was uncompromising when it came to matters of ideology and interests of the BJP, whose growth she immensely contributed to," Modi said.
"An excellent administrator, Sushma Ji set high standards in every Ministry she handled. She played a key role in bettering India's ties with various nations. As a minister we also saw her compassionate side, helping fellow Indians who were in distress in any part of the world," he said.
"Extremely shocked to hear of the passing of Smt Sushma Swaraj. The country has lost a much loved leader who epitomised dignity, courage & integrity in public life. Ever willing to help others, she will always be remembered for her service to the people of India," President Ram Nath Kovind tweeted.
Defence Minister Rajnath Singh said he was deeply shocked and anguished by the sudden demise of an extremely valued colleague.
External Affairs Minister S Jaishankar said, "Deeply shocked to learn of the passing away of Smt Sushma Swaraj. Difficult to accept this news. The whole nation grieves, the Foreign Ministry even more so."
The Congress condoled her demise.
"We are saddened to hear about the untimely demise of Smt Sushma Swaraj. Our condolences to her family and loved ones," the party said.
Swaraj had a kidney transplant in 2016 and had opted out of contesting Lok Sabha polls earlier this year for health reasons.
