New Delhi: Pakistan People Party (PPP) chief Bilawal Bhutto Zardari will accompany his father and President Asif Ali Zardari on his trip to India on Sunday, informed sources said on Saturday.

Zardari will have lunch with Prime Minister Manmohan Singh and then visit the Ajmer Sharif.

The sources said 24-year-old Bilawal, who took over as PPP chairman when he was 19 after the death of his mother Benazir Bhtto in 2007, figures in the guest list for the lunch hosted by Manmohan Singh at his Race Course Road residence.

The sources said Congress general secretary Rahul Gandhi may also be at the lunch and the two young leaders from India and Pakistan may get to talk.

Bilawal was appointed chairman of PPP December 30, 2007 when he was at Oxford. He returned to Pakistan and became active in politics last year, particularly when Zardari went for medical care to Dubai amid speculation that the president may quit.
