Whilst we welcome the eventual disclosure of SAGE participants, the fact that the delay was attributed to advice from the Centre for the Protection of National Infrastructure (CPNI) gives us cause for concern. As suggested by Professor Chris Whitty, the advice relates to emergencies relevant to national security rather than public health crises. We therefore conclude that it was not necessary for CPNI advice to have resulted in a delay in the public disclosure of SAGE participants of over three months. Within three months of this Report, the Cabinet Office should update SAGE guidance to stipulate the timeframes in which SAGE should receive advice from the Centre for the Protection of National Infrastructure, and other relevant bodies, regarding the public disclosure of expert SAGE participants.
