Much has been written about the changing role of unelected public servants in Westminster systems of government and their relationship with elected officials and the public. However, there are no studies comparing how these three groups perceive the role, and what they expect from public servants. This article provides the findings from three surveys of public servants, politicians and the public in Canada to assess how they view the role of the public servant and how this compares to different conceptions in the academic literature. The study finds that all three groups support the principles of ministerial responsibility and non-partisanship but do not believe that public servants should be anonymous and free from public scrutiny. This raises the question of whether some aspects of the traditional public servant role can be altered while keeping others in place and suggests that advocates for altering the role of the public servant will be most successful if they focus on certain aspects while preserving others.

Although science diplomacy has been gaining relevance in foreign policy to solve environmental challenges, critical questions concerning what different instruments mean under the term 'science diplomacy' and whether science diplomacy does contribute to the progress in solving environmental issues remain unanswered. We explore those questions by linking science diplomacy salient features through documentary analysis of international instruments addressing the plastics pollution in the ocean. We find that from a science diplomacy and multi-level governance perspective, the responsibilities and capabilities of emergent actors of cross-level governance are also important, leading to more attention being paid to changes in the role of national authorities, away from passive leadership to cross-cutting coalitions supported by the salient features of science diplomacy, and redefining dominant discursive approaches that have framed plastics waste.
