Congratulating the new parliament on its election, Ambassador Rehman has sent in her resignation to the Prime Minister, saying that it is time a new envoy come in as quickly as possible so that there is no gap in the relationship, an Embassy spokesman said.
A political appointee of the previous government and a close aide of Pakistan President Asif Ali Zardari, Rehman came to Washington at the time when the US-Pak relationship was at its lowest ebb in post 9/11.
Rehman had succeeded in reviving the US-Pak relationship.
