Reporter’s in contact with source on the way from France (2,5)
I believe the answer is:
en route
'reporter's in contact with source' is the definition.
I can't judge whether this definition defines the answer.
'on the way from france' is the wordplay.
'on' is a charade indicator (letters next to each other).
'the way' becomes 'route' (route is a kind of way).
'from france' becomes 'en' (I can't explain this - if you can you should believe this answer much more).
'route' put after 'en' is 'EN ROUTE'.
Can you help me to learn more?
(Other definitions for en route that I've seen before include "on the road" , "While travelling" , "March" , "On the way - in France" , "As part of a journey" .)
