Explorer from Iran risked scarf being ruined (3,7,5)
I believe the answer is:
sir francis drake
'explorer' is the definition.
(I've seen this before)
'iran risked scarf being ruined' is the wordplay.
'being ruined' indicates anagramming the letters.
'iran'+'risked'+'scarf'='iranriskedscarf'
'iranriskedscarf' with letters rearranged gives 'SIR FRANCIS DRAKE'.
'from' acts as a link.
(Other definitions for sir francis drake that I've seen before include "Navigator" , "Explorer" , "Sailor" .)
