Which committee/commission recommended incorporation of provisions relating to Fundamental Duties into the Constitution of India?

The Fundamental Duties of citizens were added to the Constitution by the 42nd Amendment in 1976, upon the recommendations of the Swaran Singh Committee that was constituted by the government earlier that year. Originally ten in number, the Fundamental Duties were increased to eleven by the 86th Amendment in 2002, which added a duty on every parent or guardian to ensure that their child or ward was provided opportunities for education between the ages of six and fourteen years.
