Stripper removing the last item: where it could happen, legally? (5)
I believe the answer is:
locus
'where it could happen legally?' is the definition.
(reference to legal term locus standi)
'stripper removing the last item' is the wordplay.
'stripper' becomes 'locust' (insects which strip areas of vegetation).
'removing the last item' means to remove the last letter.
'locust' with its final letter taken off is 'LOCUS'.
(Other definitions for locus that I've seen before include "Area of" , "Spot" , "insect" , "line" , "Particular place something is found" .)
