Rich Liberal, leading force, wanting power (4)
I believe the answer is:
lush
'rich' is the definition.
(similar in meaning)
'liberal leading force wanting power' is the wordplay.
I cannot really see how this works, but
'liberal' could be 'l' (abbreviation) and 'l' is found within the answer.
The remaining letters 'ush' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for lush that I've seen before include "Luxuriant - drunkard (slang)" , "Handsome" , "dipsomaniac?" , "Growing thickly; drunkard" , "Of growth, profuse and abundant" .)
