Declare in bad taste (5)
I believe the answer is:
state
'declare' is the definition.
(I know that declare is a kind of state)
'bad taste' is the wordplay.
'bad' indicates anagramming the letters.
'taste' is an anagram of 'STATE'.
'in' is the link.
(Other definitions for state that I've seen before include "Speak" , "Declare - political unit" , "Government; say" , "Express; pomp" , "Assert; nation" .)
