Concept:Promoting electoral integrity means ensuring elections are free, fair, credible, and transparent.
Explanation:The electoral management body is the institution responsible for organising, conducting, and overseeing elections.
It establishes electoral guidelines and monitors compliance by all political parties and candidates.
It also ensures transparency in the electoral process so that results reflect the true will of the people.
Without such a body, elections could be manipulated or lack credibility.
For example, in Nigeria, the Independent National Electoral Commission (INEC) performs this crucial role.
Civil society organisations only observe and advocate for reform.
The executive arm of government implements laws but should not control elections.
Security services provide safety but do not manage the electoral process.
Therefore, the institution that directly promotes electoral integrity is the electoral management body.
