Zimbabwe's first lady urges Robert Mugabe to name his successor

Grace Mugabe appears to contradict 93-year-old husband for first time in sign that battle to be country's next president has intensified

Zimbabwe's first lady, Grace Mugabe, has challenged her 93-year-old husband Robert to name his preferred successor as president to end deepening divisions over the future leadership of the ruling Zanu-PF party, according to state television.

Robert Mugabe, Africa's oldest leader, has ruled the former British colony since independence in 1980 but has insisted that Zanu-PF, and not him, should choose his successor.
