Renewed emphasis on chairman ultimately being crooked (9)
I believe the answer is:
misshapen
'crooked' is the definition.
(thesaurus)
'renewed emphasis on chairman ultimately' is the wordplay.
'renewed' is an anagram indicator.
'on' is a charade indicator (letters next to each other).
'ultimately' indicates one should take the final letters.
The last letter of 'chairman' is 'n'.
'emphasis' is an anagram of 'misshape'.
'misshape'+'n'='MISSHAPEN'
'being' acts as a link.
(Other definitions for misshapen that I've seen before include "Badly designed" , "Not looking round" , "showing bad form" , "Ugly in form" , "Deformed" .)
