'factually correct' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for true that I've seen before include "Corrected" , "not showing 12 [DISHONESTY]" , "Real or correct" , "Right - honourable" , "Unfeigned" .)
(Other definitions for right that I've seen before include "one side" , "Morally good, justifiable or acceptable" , "Prerogative" , "Morally good; rectify" , "Fair or just" .)
