Stick to publicity at this point (6)
I believe the answer is:
adhere
'stick to' is the definition.
(synonyms)
'publicity at this point' is the wordplay.
'publicity' becomes 'ad' (short for advertisement).
'at this point' becomes 'here' (here means in this place).
'ad'+'here'='ADHERE'
(Other definitions for adhere that I've seen before include "Stick to as by suction" , "Stick to - cement" , "Remain attached" , "Stick to, remain loyal" , "Keep" .)
