One forking out cash to engage Liberal actor, perhaps (6)
I believe the answer is:
player
'actor perhaps' is the definition.
(I know that television actor is a type of actor)
'one forking out cash to engage liberal' is the wordplay.
'one forking out cash' becomes 'payer' (someone paying for something).
'to engage' means one lot of letters goes inside another (some letters get engaged in others).
'liberal' becomes 'l' (abbreviation).
'payer' going around 'l' is 'PLAYER'.
(Other definitions for player that I've seen before include "Sportsman - instrumentalist" , "Professional musician - team sportsperson" , "Partaker in game" , "Contestant" , "One taking part in a game" .)
