STOCKSHOTS: Botswana's capital city Gaborone Botswana, a diamond-rich southern African country, has been ruled by Botswana Democratic Party since independence in 1966. It is seen as one of Africa's success stories, but the country has recorded rising unemployment since 2009 as the global economic crisis sent diamond prices falling.
