Rubbish journey back from France (5)
I believe the answer is:
tripe
'rubbish' is the definition.
(both can mean nonsense)
'journey back from france' is the wordplay.
'journey' becomes 'trip' (trip is a kind of journey).
'back from' suggests the final letters (the letter at the back of the word).
The final letter of 'france' is 'e'.
'trip'+'e'='TRIPE'
(Other definitions for tripe that I've seen before include "Rot" , "Swallowed" , "Cow's stomach lining used as food" , "Junk; food" , "Rubbish; stomach as food" .)
