People scattered seeing snake interrupt radio broadcast (8)
I believe the answer is:
diaspora
'people scattered' is the definition.
(I've seen this before)
'snake interrupt radio broadcast' is the wordplay.
'snake' becomes 'asp' (asp is a kind of snake).
'interrupt' means one lot of letters goes inside another.
'broadcast' indicates anagramming the letters (letters scattered or cast around).
'radio' anagrammed gives 'diora'.
'asp' put inside 'diora' is 'DIASPORA'.
'seeing' is the link.
(Other definitions for diaspora that I've seen before include "Scattering in exile" , "Dispersion of a people from their homeland" , "Great dispersion of people, Jews or Irish" , "race round the world" , "Scattered group" .)
