Part of brazen campaign pitch (6)
I believe the answer is:
encamp
'pitch' is the definition.
(I've seen this before)
'part of brazen campaign' is the wordplay.
'part of' says the answer is hidden in the clue.
'ENCAMP' is hidden within 'brazen campaign'.
(Other definitions for encamp that I've seen before include "Establish tented accommodation (for soldiers)" , "Lodge in tents (mil.)" , "Settle into a tent" , "Set up tents" , "Settle in tents" .)
