Reconciliation from across the Channel (13)
I believe the answer is:
rapprochement
'reconciliation' is the definition.
(I know that reconciliation can be written as rapprochement)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for rapprochement that I've seen before include "move towards peace?" , "resumption of friendly relations" , "Re-establishment of harmonious relations" , "Resumption of good relations" , "Resumption of harmonious relations" .)
