Key takeaways
- Zambia’s mixed-member proportional representation system combines first-past-the-post constituency elections with proportional representation seats.
- Constituency MPs continue to be elected directly by voters in their constituencies.
- Proportional representation seats are intended for women, youths and persons with disabilities, with allocation linked to political parties’ share of valid presidential votes.
- The model also applies at local government level, where ward-based seats remain alongside proportional representation seats for specified groups.
- For voters, the system means a single general election can shape both direct constituency representation and the proportional distribution of reserved representation seats.
Zambia’s electoral framework now combines constituency-based first-past-the-post voting with proportional representation intended to increase the representation of women, youths and persons with disabilities. Here is a practical guide to what the system means for voters, political parties and the composition of Parliament and councils.

What changed in Zambia’s electoral system?
Zambia has moved to a mixed-member proportional representation electoral framework for the National Assembly and councils. The system brings together two methods of choosing representatives. Some seats are filled through first-past-the-post contests in constituencies and wards, while another group of seats is distributed through proportional representation.
The constitutional changes were enacted in 2025, while the Electoral Process Amendment Act of 2026 provided the operational framework for the 13 August general election, the first held under the new rules. The Electoral Commission of Zambia spent the months before the poll sensitising political parties and other stakeholders on the new procedures.
First-past-the-post remains for constituency MPs
For constituency-based seats in the National Assembly, voters still elect individual candidates using the familiar first-past-the-post method. The candidate who receives the highest number of votes in a constituency wins that seat.
This preserves the direct link between an elected Member of Parliament and a defined constituency. At local government level, mayoral and council chairperson positions and ward-based councillor seats also continue to use first-past-the-post voting.
Where proportional representation comes in
The proportional representation component is designed to broaden representation for women, youths and persons with disabilities. These seats are not decided in the same way as constituency contests. Instead, they are distributed to qualifying political parties after a general election according to the prescribed rules.
Under the constitutional framework debated and adopted by the National Assembly, the Electoral Commission distributes proportional representation seats to political parties in proportion to the total number of valid votes received by their presidential candidates. The detailed nomination, party list and allocation procedures are governed by electoral legislation and regulations.
A simple way to understand the model
- Voters elect constituency representatives. Candidates contest constituency seats and the candidate with the most votes wins.
- Presidential votes also affect proportional representation. A political party’s share of valid presidential votes is used in determining its proportional allocation under the prescribed system.
- Parties use approved lists for proportional seats. Political parties participating in the proportional component submit lists in accordance with electoral rules and timelines.
- ECZ allocates the proportional seats after the election. The Electoral Commission applies the legal formula and distributes the available seats among qualifying political parties.
- The final legislature combines both types of representatives. The National Assembly therefore contains directly elected constituency MPs together with members entering through proportional representation.
Why was the mixed system introduced?
The stated objective of the reform is to improve representation in elected institutions, especially for groups that have historically been under-represented. Parliamentary records identify women, youths and persons with disabilities as the groups targeted by the proportional representation component.
Supporters of the reform argue that first-past-the-post elections can produce legislatures that do not fully reflect the diversity of the electorate. A proportional element gives political parties another route through which specified groups can enter Parliament and councils.
What does it mean for political parties?
Political parties must now pay closer attention to both constituency contests and the proportional representation rules. Their presidential vote share can affect the number of proportional seats they receive, while compliance with party-list requirements determines who is eligible to fill those seats.
This gives national vote performance an additional institutional consequence beyond the presidential race itself. It also places greater scrutiny on how parties select and rank candidates from the groups covered by proportional representation.
What does it mean for voters?
For voters, the most important point is that Zambia has not abolished constituency representation. Citizens still choose constituency MPs directly. What has changed is that the final composition of Parliament and councils now also includes a proportional component.
That makes civic education particularly important. A voter may understand who won a constituency but still need to know why additional members enter Parliament through party lists after the election. Explaining that second layer is central to understanding the new system.
What the system does not mean
Mixed-member proportional representation does not mean every parliamentary seat is filled from a party list. It also does not remove constituency voting. Zambia’s model combines direct constituency elections with a separate proportional mechanism for specified representation seats.
The economic and governance angle
Electoral rules can affect the quality and composition of public decision-making. Broader representation may bring more varied experiences into debates on the national budget, public services, employment, business regulation and social policy. The practical impact, however, will depend on how political parties nominate candidates and how effectively elected representatives use their positions.
For businesses and investors, the immediate issue is institutional clarity. Clear electoral rules and transparent seat allocation reduce uncertainty around the formation of the legislature after an election.
Civic education will remain essential
The Library Development Foundation’s civic education campaign ran ahead of the 13 August poll, the first general election held under the mixed-member proportional system. With constituency results declared, attention now turns to how the proportional seats are filled, and public understanding will depend on simple explanations of how direct seats, party lists and proportional allocation fit together.
The Electoral Commission, civil society organisations, political parties, media houses and civic education organisations therefore have a shared responsibility to explain the system accurately and consistently.
