Resented TV sites being distributed to those who benefit most (6,9)
I believe the answer is:
vested interests
'to those who benefit most' is the definition.
I can't judge whether this definition defines the answer.
'resented tv sites being distributed' is the wordplay.
'being distributed' indicates an anagram.
'resented'+'tv'+'sites'='resentedtvsites'
'resentedtvsites' with letters rearranged gives 'VESTED INTERESTS'.
Can you help me to learn more?
(Another definition for vested interests that I've seen is " groups hoping to gain advantage?".)
