I believe the answer is:

'groups' is the definition.
(I've seen this in other clues)
'in the end policies bore admit focus' is the wordplay.
'in the end' indicates one should take the final letters.
The final letters of 'policies bore admit focus' are 'SETS'.
(Other definitions for sets that I've seen before include "Places" , "Major divisions of tennis match" , "Hardens" , "Coagulates" , "Scenery etc. of 11 across productions" .)
