Local news broadcast ultimately betrays inexperience (10)

Ross

I believe the answer is:

callowness

'inexperience' is the definition.
(thesaurus)

'local news broadcast ultimately betrays' is the wordplay.
'broadcast' indicates an anagram (letters scattered or cast around).
'ultimately' indicates one should take the final letters.
The final letter of 'betrays' is 's'.
'local'+'news'='localnews'
'localnews' anagrammed gives 'callownes'.
'callownes'+'s'='CALLOWNESS'
