Voters in Botswana have rejected the country’s long-serving governing party in a result that marks a political earthquake in the diamond-rich southern African nation. The Botswana Democratic Party (BDP) - in power since independence in 1966 - has won only four parliamentary seats as of Friday afternoon. It will be replaced by the Umbrella for Democratic Change (UDC). In a phone call to UDC leader Duma Boko, President Mokgweetsi Masisi conceded and congratulated his opponent. Thabiso Tema spoke with Sonia Gaobolae, political analyst and communications and research manager for Botswana Centre for Public Integrity.
