Fruit as seen by a ruler (8)
I believe the answer is:
sultanas
'fruit' is the definition.
(I've seen this before)
'as seen by a ruler' is the wordplay.
'seen by' is a charade indicator (letters next to each other).
'a ruler' becomes 'sultan' (sultan is a kind of ruler).
'as' after 'sultan' is 'SULTANAS'.
(Other definitions for sultanas that I've seen before include "Dried fruit - female relatives of a Muslim ruler" , "Currants" , "Dried seedless grapes" , "concubines" .)
