MotivationGovernments commonly support the advocacy role of civil society organizations (CSOs) in development, but studies argue that close linkages between government and CSOs are problematic.

We also analysed CSO programmes, policy documents and publicly available information.FindingsIn Dialogue and Dissent, space for dissent, flexibility and relative equality between government and CSOs positively address mutuality and institutional pressures.
