Officials said Zardari had gone to Dubai to attend the wedding of the son of a friend and had returned as scheduled. Presidential spokesman Farhatullah Babar confirmed to the media that Zardari had travelled to Dubai to attend the
wedding and had reached Islamabad at 5 am. 

Zardari had triggered widespread speculation about his future when he abruptly travelled to Dubai last month and spent nearly a fortnight there to be treated for a heart condition. 

He made the one-day trip to Dubai after matters reached a head in the confrontation between the civilian government and the military over an alleged memo that had sought US help in reining in the army following the killing of Osama bin Laden in Pakistan in May last year.
