Iron inside poor wrought-iron hand (9)
I believe the answer is:
oppressor
'iron hand' is the definition.
(thesaurus)
'iron inside poor wrought' is the wordplay.
'iron' becomes 'press' (I've seen this in another clue).
'inside' indicates putting letters inside.
'wrought' indicates anagramming the letters (wrought means beaten into a new shape).
'poor' anagrammed gives 'opor'.
'press' put into 'opor' is 'OPPRESSOR'.
(Other definitions for oppressor that I've seen before include "Persecutor of proposers" , "One who keeps another in subjection" , "Despot" , "One tyrannises" , "One subjects others to undue pressure" .)
