Governmental bureaus (8)
I believe the answer is:
agencies
'governmental bureaus' is the definition.
'agencies' can be an answer for 'bureaus' ('agency' can be a synonym of 'bureau'). I also know that 'governmental' relates to this answer.
This is the entire clue.
(Other definitions for agencies that I've seen before include "Businesses providing specific services" , "Firms who transact business for others, perhaps actors" , "Service organisations" , "Businesses that provide services on behalf of another businesses" , "Businesses that serve others" .)
