Northern people touring edges of other county (7)
I believe the answer is:
norfolk
'county' is the definition.
(English county)
'northern people touring edges of other' is the wordplay.
'northern' becomes 'n' (abbreviation e.g. N. Ireland).
'people' becomes 'folk' (informal term for people).
'touring' is an insertion indicator (tour can mean to go around).
'edges of' means to remove the middle letters.
'other' with its middle taken out is 'or'.
'n'+'folk'='nfolk'
'nfolk' placed around 'or' is 'NORFOLK'.
(Other definitions for norfolk that I've seen before include "Broad area" , "Part of country" , "Eastern county" , "Very flat county" , "English county containing the Broads" .)
