Instead, he rested the whole day yesterday, reportedly on the advice of doctors.
"President Zardari is not feeling well. But there is nothing serious with his health", a member of the President's media team told PTI.
He was scheduled to attend the founder's day function of the renowned Aitchison College and to meet leaders of his Pakistan People's Party.
Zardari is staying at Bilawal House, his new private bomb-proof residence spread over 25 acres at Bahria Town and reportedly gifted to him by property tycoon Malik Riaz Hussain.
Prime Minister Raja Pervez Ashraf, Kashmir Affairs Minister Manzoor Wattoo and Water Minister Chaudhry Ahmad Mukhtar were among those who called on Zardari last night to inquire after his health.
