A United Nations inquiry into the December 2007 assassination of the former Pakistani Prime Minister Benazir Bhutto begins today. Bhutto was murdered in a suicide attack at a rally as she campaigned for election. Her death threw nuclear-armed U.S. ally Pakistan into crisis and her Pakistan People’s Party rode a wave of sympathy to win a February 2008 election. Her widower, Asif Ali Zardari, later become President. As the commission investigating her murder gets underway, we ask whether they have enough power to get even close to the truth? The BBC’s World Affairs Correspondent Mike Wooldridge, who is in Islamabad, Pakistan, joins us with more.
