African country runs out of green vegetable (4)
I believe the answer is:
chad
'african country' is the definition.
(Chad is an example)
'runs out of green vegetable' is the wordplay.
'runs' becomes 'r' (cricket abbreviation).
'out of' is a deletion indicator.
'green vegetable' becomes 'chard' (I've seen this before).
'chard' with 'r' removed is 'CHAD'.
(Other definitions for chad that I've seen before include "Country - which got Bush elected in Florida?" , "Feature of controversial election once" , "Large, shallow lake in north central Africa" , "Central African republic, capital N'Djamena" , "North central African country, capital N'Djamena" .)
