South Africa’s President Cyril Ramaphosa vowed to attain “hope and renewal” as he was inaugurated at a stadium in the capital Pretoria.
The African National Congress (ANC) leader vowed to fight corruption and rejuvenate the struggling economy.
Ramaphosa was elected earlier this month with a majority of 57.5%, the smallest since the party came to power 25 years ago.
Mr Ramaphosa initially took over from Jacob Zuma in 2018 after Mr Zuma was accused of corruption.
