President Zardari leaves for Dubai

Pakistani President Asif Ali Zardari has left for Dubai on Thursday for further medical check-ups following his admission to hospital there last month for heart treatment, spokesperson said.The planned trip comes at time when President Zardari is facing growing threats over a memo allegedly crafted by his former ambassador to the United States Hussain HAqqani seeking help in preventing a coup by Pakistans powerful generals.Presidential Spokesperson said that President Asif Ali Zardari went to Dubai for a one-day trip.He was released from a Dubai hospital last month after being treated for what Pakistani officials said was a transient ischemic attack, in which blood supply to a part of the nervous system is cut off, but not for long enough to kill tissue as in a stroke.His trip to Dubai in December had triggered speculation that he might resign.
