Old tyrant uses handmaid's pants (6,7)
I believe the answer is:
saddam hussein
'old tyrant' is the definition.
I don't know anything about this answer so I can't tell whether this works.
'uses handmaid's pants' is the wordplay.
'pants' is an anagram indicator (UK informal term for 'nonsense' or 'rubbish').
'uses'+'handmaids'='useshandmaids'
'useshandmaids' with letters rearranged gives 'SADDAM HUSSEIN'.
Can you help me to learn more?
(Another definition for saddam hussein that I've seen is " Former dictator - USA hid madness (anag)".)
