Pakistan President Signs Amendment Curbing Powers VOA News 19 April 2010 Pakistani President Asif Ali Zardari has signed a constitutional amendment that strips him of sweeping powers. Mr. Zardari signed the 18th Amendment into law Monday in a ceremony at his presidential office in Islamabad. Both the lower and upper houses of parliament approved the package, which makes Mr. Zardari a ceremonial head of state by transferring key powers to the office of the prime minister and the parliament. They include the ability to dismiss an elected government, dissolve the parliament and appoint military chiefs. The additional presidential powers were introduced by military dictator Mohammad Zia-ul-Haq in the 1980s. The amendment also renames Pakistan's North West Frontier Province as "Khyber Pakhtunkhwa" to reflect the ethnic Pashtun group that dominates the region. The move has sparked protests by Urdu speakers who oppose the name change.  Some information for this report was provided by AP, AFP and Reuters. .
