'subject' is the definition.
(I've seen this in another clue)

I can't explain the rest of the clue.

(Other definitions for liege that I've seen before include "Belgian city or ancient lord" , "Large Belgian city" , "Feudal vassal from a Belgian city" , "Sort of lord" , "Bound to render feudal service" .)

I've seen this clue in the Sydney Morning Herald.
