Stephen Sackur presents a special HARDtalk from the Zimbabwean capital Harare. For the past 35 years Zimbabwe has been dominated by one man - Robert Mugabe. Hero of the liberation struggle, all-powerful president and, for some in the west, a pariah. But he is now 91 years of age. Stephen Sackur talks to influential and outspoken information minister Jonathan Moyo and asks if he thinks there can be a peaceful transition in Zimbabwe.
