The Chief of Staff Dataset, 1990–2024 (to Westminster Prime Ministers)

This dataset accompanies the monograph, Chief of Staff: The Rise of Political Craft in Westminster Democracies (Pickering, 2025). The dataset contains biographical, demographic, and contextual political information on 65 chiefs of staff appointed to prime ministers between 1990 and 2024 in four Westminster family democracies: Australia, Britain, Canada, and New Zealand. In addition, the dataset presents annual lists of all “political advisers” in the four countries.
