Foolishly charmed by English political manoeuvre (8)
I believe the answer is:
demarche
'political manoeuvre' is the definition.
'foolishly charmed by english' is the wordplay.
'foolishly' indicates an anagram.
'by' means one lot of letters go next to another.
'english' becomes 'e' (abbreviation).
'charmed' is an anagram of 'demarch'.
'demarch'+'e'='DEMARCHE'
(Other definitions for demarche that I've seen before include "Mad cheer for diplomatic manoeuvre" , "A move or countermove in diplomatic relations" , "A political initiative" , "Diplomatic protest or manoeuvre" , "A diplomatic initiative" .)
