Angola's political opposition have accused the National Electoral Commission (CNE) of irregularities ahead of general polls set for late August. 'We call on the CNE to take the necessary decisions to correct these irregularities to ensure that the electoral process is truly free, fair and transparent,' said Abel Chivukuvuku, president of the Broad Convergence of Angolan Salvation (Casa) coalition after meeting the CNE. 'The number of voters is unclear, the CNE cannot say how early or foreign voting will be organised, or give the publication date of the voters' roll.'
