Publicity is about to create stir (6)
I believe the answer is:
prison
'stir' is the definition.
(I've seen this before)
'publicity is about' is the wordplay.
'publicity' becomes 'pr'.
'about' becomes 'on'.
'pr'+'is'+'on'='PRISON'
'to create' is the link.
(Other definitions for prison that I've seen before include "Place of incarceration" , "Gaol" , "Stir - can" , "No rips (anag)" , "cage" .)
