This chapter has two aims. First, we describe the Swedish authorities’ management of the pandemic in 2020. Their approach deviated markedly from policies pursued in neighbouring countries, with respect to the authorities’ understanding of the virus; the measures adopted to counter the spread of the virus; the reliance on recommendations to citizens rather than legally binding instructions; and, most notably, the extensive delegation of policy-making by the government to a technocratic authority, the Public Health Agency. Second, we try to explain this policy deviation. We show that Swedish constitutional arrangements, with relatively autonomous, policy-delivering agencies, are a necessary but insufficient condition for explaining the outcome. Three additional conditions are needed: assertive leadership within the Public Health Agency; a weak and passive government; and citizens’ trust in public institutions, reflected in rallying around the flag and in supportive media coverage, all which cemented initial policy choices.
