Country’s circulating report, impressing journalist (6)
I believe the answer is:
sweden
'country's' is the definition.
(Sweden is an example)
'circulating report impressing journalist' is the wordplay.
'circulating' says the letters should be written backwards.
'report' becomes 'news' ('news report' can be a synonym of 'report'**).
'impressing' indicates putting letters inside (impress historically meant to conscript).
'journalist' becomes 'ed' (short for editor).
'news' placed around 'ed' is 'nedews'.
'nedews' written backwards gives 'SWEDEN'.
(Other definitions for sweden that I've seen before include "We send out to here, oddly" , "N. European country" , "North European country" , "land" , "Baltic country" .)
