Asian travelling back through Jaffna in a rickshaw (7)
I believe the answer is:
iranian
'asian' is the definition.
(I know that Iranian is a type of asian)
'travelling back through jaffna in a rickshaw' is the wordplay.
'travelling back' says the letters should be written backwards.
'through' indicates the answer is hidden within the clue.
'nainari' can be found hidden inside 'jaffna in a rickshaw'.
'nainari' written backwards gives 'IRANIAN'.
(Other definitions for iranian that I've seen before include "Foreign national" , "Eg, native of Teheran" , "One from Tehran, say" , "One from Isfahan" , "Asian citizen" .)
