Dictator imprisoning Sudanese leader in warehouse (6)
I believe the answer is:
despot
'dictator' is the definition.
(despot is a kind of dictator)
'sudanese leader in warehouse' is the wordplay.
'leader' suggests taking the first letters.
'in' means one lot of letters goes inside another.
'warehouse' becomes 'depot' (I've seen this before).
The initial letter of 'sudanese' is 's'.
's' put within 'depot' is 'DESPOT'.
'imprisoning' acts as a link.
This may not be right. It may belong to another bit of the clue.
(Other definitions for despot that I've seen before include "monster?" , "Posted to tryant" , "Cruel and oppressive ruler" , "who treats others badly?" , "has first of shocks in store" .)
