Attraction of corporation on the rise (3)
I believe the answer is:
tug
'attraction' is the definition.
(thesaurus)
'corporation on the rise' is the wordplay.
'corporation' becomes 'gut' (both can humorously mean belly fat).
'on the rise' says the letters should be written backwards (in a down clue, letters go up).
'gut' backwards is 'TUG'.
'of' is the link.
(Other definitions for tug that I've seen before include "Tow (of war?)" , "Pull; loop on saddle" , "Pull suddenly; boat" , "Haul" , "Pull vigorously, yank" .)
