Announcement and declaration results
At a polling station
The Presiding Officer announces election results at the polling station. This is done outside the entrance of the polling station. A copy of the polling station results form is posted on the wall outside the polling station for the general public to see.
At a totaling center
The Returning Officer is responsible for adding up results from all polling stations in a constituency. The Returning Officer announces and adds polling station results as they are received. The totaling of results is done in the presence of accredited political party agents, media, election monitors and observers. When all the polling station results have been added, the Returning Officer declares the winners of National Assembly, Mayor/Chairperson and Councilor Elections. The Presidential results are also announced but not declared. Results are then transmitted electronically to the National Results Centre in Lusaka.
