Former cricketer Imran Khan took oath today to become Pakistan's Prime Minister, ending decades of political dominance by Pakistan's two dynastic powerhouses. Mr Khan had run a populist campaign promising to change the lives of Pakistanis and come down hard on corruption. "Those people who have looted the country, I promise that they will be brought to justice," Mr Khan reiterated on Friday after winning the acrimonious vote in parliament for the top seat. A tearful Mr Khan, clad in a traditional black sherwani, smiled as he stumbled over some of the words of the oath administered to him by President Mamnoon Hussain during the ceremony, televised live by the state broadcaster PTV.
