If your PC is a Smaller Authority (probably not if you have a Engagement Manager) then they need to comply with the Transparency Code for Smaller Authorities.
Section 30 of this code requires "Smaller authorities should also publish meeting agendas, which are as full and informative as possible, and associated meeting papers not later than three clear days before the meeting to which they relate is taking place"
I vaguely recall that there is something in some act of law somewhere that also requires this of none Smaller Authorities. If i find it i'll post it - but i might be imagining it.
All PC's should, by law, have published a Publication Scheme on their website that specifies the documents that are available to the public. The model publication scheme published by the ICO specified 'reports presented to council meetings'. So check your PC's scheme and see what it says about this. Complain to the ICO if they are not complying.
