Condoling Khushwant Singh's death, President Pranab Mukherjee described him as a "fearless intellectual" who had sharp insight and unique wit, as well as sense of humour.

In a condolence message sent to his son Rahul, the President said he was deeply saddened to learn about the passing away of Singh.

Terming him as a prolific writer who made his mark in literature as well as journalism, the President said, "Singh will be remembered for his sharp insight and unique wit, as well as sense of humour."
