People in Angola are voting in a general election which is expected to be the most closely fought since its independence in 1975.
In the race for the presidency, incumbent João Lourenço of the governing MPLA faces the leader of the one-time rebel group Unita, Adalberto Costa Júnior.
The MPLA, which has been in power for more than four decades, has been criticised for not tackling high levels of inflation, poverty and unemployment.
President Lourenço has promised to reform Angola’s oil-driven economy but correspondents say many voters may not believe him as reported by BBC.
