Lazt government committees (and local government committees) pretty much allow the civil servants to write the reports for them.
It goes something like this:
Civil servants write a brief
Committee meets to agree it
Civil servants draft a list of witnesses in consultation with the Chair
Committee meets and 'takes evidence'
Civil servants write up report
Committee meets to discuss it
Civil servants produce final report
Committee meets to sign it off
Chair is 'exhausted' by all her hard work
If a single one of those civil servants has an agenda, or an area of incomptence, and the Chair doesn't know their shit, then that agenda / incompetence leaks into every aspect of the final report, because it's been there since the initial brief stage and has stayed there throughout, like a virus.
Modern civil servants are woke as fuck, have been indoctrinated into Stonewall Law, and are not great critical thinkers.
