After last month real reform for state (7)
I believe the answer is:
declare
'for state' is the definition.
(declaring is a kind of stating)
'after last month real reform' is the wordplay.
'after' is a charade indicator (letters next to each other).
'last month' becomes 'dec' (short for December, last month of the year).
'reform' indicates anagramming the letters (letters in a new form).
'real' with letters rearranged gives 'lare'.
'dec' next to 'lare' is 'DECLARE'.
(Other definitions for declare that I've seen before include "Profess" , "Assert" , "Make clearly known" , "Make a statement, to customs perhaps" , "Announce; end innings" .)
