Political label curtailed (3)
I believe the answer is:
lab
'political label' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for lab that I've seen before include "Scientists' workplace" , "Room for scientist" , "SECOND PART OF 15" , "Research workroom" , "biology classroom?" .)
