Party’s place for research (3)
I believe the answer is:
lab
I believe this clue is a double definition.
'party's' is the first definition.
(abbreviation for Labour)
'place for research' is the second definition.
(I've seen this in another clue)
(Other definitions for lab that I've seen before include "SECOND PART OF 15" , "retriever" , "Dog" , "Science room" , "biology classroom?" .)
