“… councils who simply get a local person to sign the form without undertaking the work...”
Yes, seen it done.
Cllrs don’t want an IA that tells them they are inept. Auditors know if they submit a critical report their income stream will be curtailed.
Experienced 1 local clerk who was providing IA to numerous local PCs and they were ALL completely inept.
Cllrs didn’t (want to) know, just happy to be told everything is OK so that they could parrot the inept IA findings onto the AGAR.
DREADFUL state of affairs.
