Badger from cluster produced by Animal Right's activists, for one (8,5)
I believe the answer is:
pressure group
'badger from cluster' is the definition.
The answer and definition can be both groups as well as being singular nouns.
Maybe there's a link between them I don't understand?
'animal right's activists for one' is the wordplay.
I cannot quite see how this works, but
'for one' could be 'eg' (I've seen this in other clues) and 'eg' is found within the answer.
'right' could be 'r' (common abbreviation) and 'r' is present in the answer.
This explanation may well be incorrect...
'produced by' acts as a link.
Can you help me to learn more?
(Other definitions for pressure group that I've seen before include "People promoting a particular view" , "Campaigners" , "Policy promoters" , "Body promoting cause" , "Campaigning body" .)
