Obscure end eg Dina had? (6,6)

I believe the answer is:
hidden agenda
'obscure end eg dina had?' is the definition.
I don't know anything about this answer so I can't judge whether this works.
'obscure end eg dina had?' is the wordplay.
'obscure' is an anagram indicator.
'end'+'eg'+'dina'+'had'='endegdinahad'
'endegdinahad' with letters rearranged gives 'HIDDEN AGENDA'.
Can you help me to learn more?
(Other definitions for hidden agenda that I've seen before include "Sub-text, unstated objective" , "Secret motive behind one's actions" , "Undisclosed reason" , "that could delay the meeting?" , "Ulterior motive" .)
