Like the Trumpton fire brigade, Britain’s disaster planners have had precious little opportunity to show off their skills over the past few decades. Plans for a nuclear war merely gathered dust. Global pandemics failed to arrive, as did a no-deal Brexit. Just about the only crisis requiring nationwide emergency planning concerned foot and mouth disease in 2001 when six million animals were slaughtered and Labour ministers announced ‘the countryside is closed’, killing off rural businesses, yet still failed to prevent the spread of the disease from Cornwall to Northumberland.
