Serial broadcast in Middle Eastern country (6)
I believe the answer is:
israel
'middle eastern country' is the definition.
(country in the Middle East)
'serial broadcast' is the wordplay.
'broadcast' indicates anagramming the letters (letters scattered or cast around).
'serial' is an anagram of 'ISRAEL'.
'in' is the link.
(Other definitions for israel that I've seen before include "Jewish republic" , "Middle-Eastern state" , "Go to this country for ale, sir" , "Middle Eastern state" , "Large bird cage" .)
