Staff involved in producing I’m A Celebrity (4)
I believe the answer is:
mace
'staff' is the definition.
(mace is a kind of staff)
'involved in producing i'm a celebrity' is the wordplay.
'involved in' indicates the answer is hidden within the clue.
'MACE' can be found hidden inside 'producing im a celebrity'.
(Other definitions for mace that I've seen before include "Medieval weapon or kind of spice" , "put on the rack?" , "Staff - ground nutmeg" , "Tear gas - spice" , "something fragrant" .)
