Removing restraints in county in Germany (7)
I believe the answer is:
untying
'removing restraints' is the definition.
(removing ties)
'in county in germany' is the wordplay.
'in' indicates a hidden word.
'UNTYING' is hidden in the letters of 'county in germany'.
(Other definitions for untying that I've seen before include "Loosening a knot" , "Removing restrictions" , "Releasing fastenings" , "Undoing, unfastening" .)
