Kofi Annan – Former UN Secretary General (1997-2006)

World figures have been paying tribute to the former UN secretary-general and Nobel laureate Kofi Annan, who has died at the age of 80. HARDtalk’s Zeinab Badawi spoke to him in April at a special event to mark his birthday and the tenth anniversary of the Kofi Annan Foundation. In a career spanning six decades at the United Nations, he held several senior positions including two terms as Secretary-General. There were high points such as the award of the Nobel Peace Prize as well as tragic events such as the Rwandan genocide and the Srebrenica massacre of Bosnian Muslims. But what were his biggest worries and did he have any regrets?Image: Kofi Annan (Credit: Getty Images)
