'Memogate': Haqqani in Pakistan to explain his position

The air is rife with tension in Pakistan after a secret memo, allegedly sent by Pakistan President Asif Ali Zardari to the US warning of and seeking assistance against a possible military takeover after Osama bin Laden was killed in Pakistan, in May this year. The memo was purportedly written by Pakistan's envoy to the US, Husain Haqqani, on behalf of President Zardari. To clear his name of involvement in the delivery of this memo, Mr Haqqani is in Islamabad.
