The result was devastating with town centres closed, hospitals quarantined, transport and businesses affected, a £10m clean-up bill and three people seriously ill with one fatality. More importantly, it created palpable fear in the population. Every terrorist group in the world now knows how to disrupt the UK easily, if they have a delivery system. The food and water distribution network provide a simple accessible delivery system, most of which is unguarded. It is a matter of grave concern to the intelligence services.
This is not a new threat, but it is a significantly enhanced threat since Skripal, and an attack will occur. This is not to minimise the risks from rogue employees, pressure groups and ideologically motivated individuals, but the solution as far as there is one lies in taking adequate precautions based on comprehensive intelligence.
