The Ghana Police Service has been ranked as the most corrupt public institution in the country, according to the latest 2026 Corruption Perception Index released by Global Info Analytics.
The report, published in June 2026, also placed the Ghana Immigration Service (GIS) second on the list, while business executives emerged among the most poorly rated groups for the first time.
According to the index, which was released by the Executive Director of Global Info Analytics, Mussa Dankwah, institutions were assessed based on public perceptions of corruption.
The survey ranked the Ghana Police Service as the most corrupt institution with a score of 6.45, followed by the Ghana Immigration Service with 5.69.
Business executives were ranked third with a score of 5.45, ahead of the judiciary (5.41), the Ghana Revenue Authority (5.35), Metropolitan, Municipal and District Assembly (MMDA) officials (5.24), traditional leaders (5.14), the Electoral Commission of Ghana (5.08), the Ghana Prisons Service (5.01), and Parliament (4.95).
The report identified the following as the 10 institutions perceived to be the most corrupt in Ghana:
- Ghana Police Service – 6.45
- Ghana Immigration Service – 5.69
- Business Executives – 5.45
- Judiciary – 5.41
- Ghana Revenue Authority – 5.35
- MMDA Officials – 5.24
- Traditional Leaders – 5.14
- Electoral Commission of Ghana – 5.08
- Ghana Prisons Service – 5.01
- Parliament – 4.95
On the other hand, ministers and government officials were perceived as the least corrupt, recording a score of 4.54. They were followed by the presidency (4.84), the military (4.90), and religious leaders (4.94).
Commenting on the findings, Dankwah noted that although the Police Service and Immigration Service retained the top two positions, both institutions recorded improved scores compared to previous surveys, suggesting some progress in efforts to address corruption concerns.
“The corruption perception index for June 2026 shows the least perceived corrupt institutions in Ghana are ministers/government officials, the presidency and the military. The most corrupt is still the Ghana Police, Ghana Immigration Service and now business executives who have sunk low for the first time,” he stated.
He further observed that ministers and government appointees improved their ratings compared to the previous poll. However, he pointed out that the presidency recorded a slight decline, with its score increasing from 4.77 in March 2026 to 4.84 in June 2026.
“Though the Ghana Police Service and the Immigration Service retained the number one and two spots, their overall score improves, suggesting something good might be happening in those services. While ministers/government appointees’ score improved compared to the last poll, the presidency actually deteriorated, moving from a low score of 4.77 in March to 4.84 in June 2026. They must be on the watchout,” Dankwah said.
The latest index highlights continuing public concerns about corruption in key state institutions while also indicating signs of improvement in some sectors.
