Orders forecasts, ignoring public relations (6)
I believe the answer is:
edicts
'orders' is the definition.
('edict' can be a synonym of 'order')
'forecasts ignoring public relations' is the wordplay.
'forecasts' becomes 'predicts' ('predict' can be a synonym of 'forecast').
'ignoring' is a deletion indicator.
'public relations' becomes 'pr'.
'predicts' with 'pr' taken out is 'EDICTS'.
(Other definitions for edicts that I've seen before include "Orders proclaimed by authorities" , "'Decrees, orders (6)'" , "'Decrees, fiats (6)'" , "Orders proclaimed by an authority" , "Official orders or proclamations" .)
