Mogul governor (5)
I believe the answer is:
nawab
'mogul governor' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for nawab that I've seen before include "Native governor in India; bwana (anag.)" , "Muslim nobleman" , "Indian governor" , "Governor in Mogul empire" , "Old governor" .)
