This study investigates the impact of internal organisational politics within the South African Police Service (SAPS) in the Northern Cape, focusing on political interference, nepotism, favouritism, corruption, and unfair promotion practices. The research aims to examine how these dynamics affect professionalism, morale, organisational culture, operational effectiveness, and public trust. Political influence and internal organisational politics in SAPS undermine merit-based promotion, ethical leadership, and operational cohesion. In the Northern Cape Province, where administrative structures are smaller and networks of influence closely intertwined, these practices have exacerbated low morale, factionalism, and weakened public confidence in policing. Despite existing oversight mechanisms, challenges persist, limiting SAPS’ ability to operate efficiently and maintain community trust. A qualitative case study design was adopted, employing a systematic approach. Data were collected through semi-structured interviews with SAPS officers, community policing forum (CPF) members, local leaders, and provincial officials, supplemented with focus group discussions and secondary sources such as policy documents and oversight reports. Thematic analysis was used to identify patterns and co-impact effects of internal politics, with triangulation employed to enhance reliability and validity. Ethical protocols, including informed consent, confidentiality, and neutrality, were strictly observed. The study revealed that political interference, nepotism, and corruption collectively undermine meritocracy, reduce morale, foster factionalism, and erode organisational integrity. Unfair promotion practices and opaque decision-making processes contribute to low staff motivation and disengagement. Weak oversight mechanisms and delayed accountability exacerbate these challenges. The co-impact of these factors extends beyond SAPS, affecting community trust, collaborative policing initiatives, and governance in the Northern Cape Province. The research underscores the need for transparent, merit-based promotion systems, strengthened oversight, ethical leadership, political neutrality, and multi-stakeholder engagement, including SAPS, government departments, political parties, community leaders, civil society, and religious institutions. Addressing internal organisational politics holistically is critical to improving operational effectiveness, staff morale, and public confidence in policing.
