Elect to go back (6)
I believe the answer is:
return
I believe this clue is a double definition.
'elect' is the first definition.
(returning is a kind of electing)
'go back' is the second definition.
(I've seen this before)
'to' is the link.
(Other definitions for return that I've seen before include "Homecoming" , "Two-way ticket" , "reply" , "Come/go back" , "hit back?" .)
