New Delhi: The final journey of former Prime Minister Manmohan Singh began from the AICC headquarters on Saturday morning after Congress leaders paid homage to their departed leader.

The flower-bedecked vehicle carrying the mortal remains of Singh left the Congress headquarters in a procession amid chants of "Manmohan Singh Amar Rahe".

A large number of Congress workers and leaders along with hundreds of Singh's well-wishers walked along as "Jab tak suraj chand rahega, tab tak tera naam rahega" slogans rent the air.

Former Congress chief and Leader of Opposition in Lok Sabha, Rahul Gandhi, also accompanied the procession alongside Singh's relatives.

Singh's mortal remains were taken to the AICC headquarters from his residence on 3, Motilal Nehru Road a little before 9 AM.

The mortal remains were kept inside the AICC headquarters for about an hour, with several top leaders of the Congress, including Mallikarjun Kharge, Sonia Gandhi and Rahul Gandhi, paying their last respects, among others.

Singh's wife Gursharan Kaur and one of his daughters also laid a wreath on his body and paid their last respects.

Former Rajasthan chief minister Ashok Gehlot, Congress MP Sukhjinder Singh Randhawa and several ex-Union ministers were among those who paid tributes to the former PM.
