Husain Haqqani, Pakistan's ambassador to the US, met Asif Ali Zardari here in Islamabad early Sunday over a secret memo to Washington claiming that the President had feared a military coup. A private TV reported that Haqqani arrived at the presidency and held informal talks with Zardari. Haqqani flew in to Islamabad on a flight via Qatar shortly after 2 am this morning. The envoy left the airport without speaking to the waiting media and reportedly went straight to the presidency.
