Material broadcast in disputed region (7)
I believe the answer is:
kashmir
'disputed region' is the definition.
'material broadcast' is the wordplay.
I cannot quite see how this works, but
'material' could be 'ash' (ash is a kind of material) and 'ash' is located in the answer.
This explanation may well be incorrect...
'in' is the link.
Can you help me to learn more?
(Other definitions for kashmir that I've seen before include "Himalayan region" , "State" , "Region claimed by both India and Pakistan" , "disputed Asian region" , "Subcontinental border region" .)
