Global flier (8)
I believe the answer is:
circular
I believe this is a double definition.
'global' is the first definition.
('circular' can be similar in meaning to 'global')
'flier' is the second definition.
('circular' can be a synonym of 'flier')
(Other definitions for circular that I've seen before include "Round - pamphlet" , "Leaflet for mass distribution" , "Notice for wide distribution" , "Round kind of bulletin?" , "Letter or notice copied to a number of people" .)
