I welcome the challenge from the noble Lord, but the examples we have given are also more recent, from the 2009 swine flu attack. The protocols were also used in the Salisbury Novichok attack. I know from my own experience that public
health disasters can throw up extremely unexpected hurdles and barriers to action, in the form of legislative surprises. Therefore, these powers are not considered to be frequently used. In fact, they are never used—noble Lords will all breathe a sigh of relief—but public health challenges are likely to be a feature of the future, and it is prudent to put in place the protections we need in order to provide for them.
