Poor relation from the East (8)
I believe the answer is:
oriental
'from the east' is the definition.
(I've seen this before)
'poor relation' is the wordplay.
'poor' is an anagram indicator.
'relation' is an anagram of 'ORIENTAL'.
(Other definitions for oriental that I've seen before include "Of the eastern or Asian world" , "Relation? (anagram)" , "Maybe Chinese" , "Easterner" , "Non-European" .)
