When it comes to political-administrative relations, New Public Management has aimed for a stronger diff erentiation between political and administrative matters and for an empowerment of the administration towards the political level. Th is article investigates the perceived degree of administrative discretion at the municipal level in the Flemish region of Belgium. We use data from a survey with Flemish municipal CEOs from 2019. Th e results suggest that the degree of administrative discretion in Flemish municipalities is relatively high during policy preparation. Nevertheless, during other phases of the policy cycle most municipal CEOs perceive a certain political impact on the functioning of their administration, which reaches further than steering on the main policy lines. Second, a majority identifi es a lack of mutual trust between the executive board and the administrators. Furthermore, administrative discretion increases with the size of the municipality and the assessed capacity of the administration. Also in municipalities where the key actors of political-administrative relationships remained unchanged for a longer period, the administration has more leeway to act. Lastly, the results nuance the impact of the municipal fi nancial situation and the composition of the majority on the degree of administrative discretion
