Restraint of newspapers in region with no golf (10)
I believe the answer is:
repression
'restraint' is the definition.
(thesaurus)
'newspapers in region with no golf' is the wordplay.
'newspapers' becomes 'press' (I've seen this before).
'in' indicates putting letters inside.
'with no' suggests deleting specific letters.
'golf' becomes 'g' (phonetic alphabet: alpha, bravo, charlie etc.).
'region' with 'g' removed is 'reion'.
'press' placed into 'reion' is 'REPRESSION'.
'of' is the link.
(Other definitions for repression that I've seen before include "Forcible subduing" , "Inhibition" , "Forcible prevention" .)
