Newspapers got round belonging to state (7)
I believe the answer is:
profess
'state' is the definition.
(both can mean to declare)
'newspapers got round belonging to' is the wordplay.
'newspapers' becomes 'press' (the press is the newspaper industry).
'got round' indicates putting letters inside (some letters go round others).
'belonging to' becomes 'of' ('of' can mean 'belonging to' or 'owned by').
'press' enclosing 'of' is 'PROFESS'.
(Other definitions for profess that I've seen before include "Affirm, acknowledge" , "State openly" , "Declare openly" , "Affirm faith in (religion)" , "Claim or declare" .)
