The challenge for experts in government is often described as one of speaking unwelcome truths to a resistant power. Yet, just as problematic can be instances where the advice is welcome and so left unchallenged. Two such cases in which the UK government followed flawed expert advice are considered: intelligence assessments and military advice leading up to the 2003 Iraq War and the role of SAGE (the Scientific Advisory Group for Emergencies) during the first stages of the Covid-19 pandemic in 2020. Governments need to interrogate advice and make sure that they understand its underlying assumptions and implications. It remains vital to protect the independence of the experts, but to get the best out of their advice early and active political engagement is required rather than an arms-length relationship.
