Anger about Government's rubbish (5)
I believe the answer is:
bilge
'rubbish' is the definition.
(I've seen this before)
'anger about government's' is the wordplay.
'anger' becomes 'bile'.
'about' is an insertion indicator.
'government' becomes 'g'.
'bile' placed around 'g' is 'BILGE'.
(Other definitions for bilge that I've seen before include "Rubbish like waste water in ship" , "Piffle - part of hull" , "(Water at) bottom of ship" , "Lowest internal portion of a ship's hull" , "Filthy water that collects in the bottom of a boat" .)
