She owns media, buries extraordinary report involving Indian leader! (12)
I believe the answer is:
proprietress
'she owns' is the definition.
I can't tell whether this definition defines the answer.
'media buries extraordinary report involving indian leader' is the wordplay.
'media' becomes 'press' (I've seen this before).
'buries' means one lot of letters goes inside another.
'extraordinary' indicates an anagram.
'involving' means one lot of letters goes inside another.
'leader' indicates taking the first letters.
The first letter of 'indian' is 'i'.
'report' with letters rearranged gives '[report]'.
'press' placed around '[report]' is 'p[report]ress'.
'propretress' going around 'i' is 'PROPRIETRESS'.
Can you help me to learn more?
(Other definitions for proprietress that I've seen before include "Possessive female" , "She owns a business" .)
