Independent is carrying leader on Rupert Murdoch (4)
I believe the answer is:
iris
'murdoch' is the definition.
(author Iris Murdoch)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for iris that I've seen before include "Female" , "Flag - part of eye" , "Garden flower - part of eye" , "Flag or flower in the eye" , "Ms Murdoch" .)
