Happen to receive bakery product for tenant (8)
I believe the answer is:
occupier
'for tenant' is the definition.
(thesaurus)
'happen to receive bakery product' is the wordplay.
'happen' becomes 'occur' (synonyms).
'to receive' indicates putting letters inside.
'bakery product' becomes 'pie' (I've seen this in another clue).
'occur' placed around 'pie' is 'OCCUPIER'.
(Other definitions for occupier that I've seen before include "One in possession of property" , "Squatter" , "Resident" , "One inhabiting a place" , "One in residence" .)
