The mourners at the burial grounds included Union Home Minister L K Advani, Delhi Lt Governor Vijai Kapoor, Home Secretary B P Singh, Congress Leader Jag Parvesh Chandra and Member of Parliament Waseem Ahmed.

Khan, who was 54 years old, died of a cardiac arrest last evening. Khan, who is survived by his wife and two daughters, had been Joint Secretary in the Prime Minister's office during P V Narasimha Rao's tenure.

An IAS officer of the 1967, he steered the NDMC into a profitable and efficient organisation. Under his chairmanship, the civic body, came out with a Citizen's Charter. The body was earlier taken to the NDMC headquarters at Palika Sadan to enable employees to pay homage. On a request from the New Delhi Trader's Association, the body was taken in a convoy through Connaught Place and then to the burial grounds for the funeral.

All offices of the NDMC and the Delhi State Industrial Development Corporation (DSIDC), of which Khan had been the Managing Director, remained closed today as a mark of respect. A prayer meeting will be held at Khan's Ashoka Road residence tomorrow morning.

Earlier in the day, thousands of people -- including Chief Minister Sahib Singh Verma, Congress leaders H K L Bhagat, Sajjan Kumar and Tajdar Babbar, former J&K governor Jagmohan, and former Delhi police commissioners M B Kaushal and Mikhil Kumar -- went to pay their respects to the late bureaucrat at his Ashoka road residence. Leaders of all religious faiths and people from all walks of life also visited the residence to pay their respects.
