In August 2020 the UK government announced without warning the abolition of Public Health England (PHE), the principal UK agency for the promotion and protection of public health. We undertook a research programme seeking to understand the factors surrounding this decision. While the underlying issues are complex two competing interpretations have emerged: an 'official' explanation, which highlights the failure of PHE to scale up its testing capacity in the early weeks of the COVID-19 pandemic as the fundamental reason for closing it down and a 'sceptical' interpretation, which ascribes the decision to blame-avoidance behaviour on the part of leading government figures. This paper reviews crucial claims in these two competing explanations exploring the arguments for and against each proposition. It concludes that neither is adequate and that the inability adequately to address the problem of testing (which triggered the decision to close PHE) lies deeper in the absence of the norms of responsible government in UK politics and the state. However our findings do provide some guidance to the two new organizations established to replace PHE to maximize their impact on public health. We hope that this information will contribute to the independent national COVID inquiry
