Spread out to lead spy astray (7)
I believe the answer is:
splayed
'spread out' is the definition.
(I've seen this in another clue)
'lead spy astray' is the wordplay.
'astray' indicates an anagram.
'lead'+'spy'='leadspy'
'leadspy' with letters rearranged gives 'SPLAYED'.
'to' acts as a link.
(Other definitions for splayed that I've seen before include "with legs apart" , "Turned out" , "Spread apart" .)
