Losing coordination with European drink (4,3)
I believe the answer is:
sloe gin
'drink' is the definition.
(sloe gin is a kind of drink)
'losing coordination with european' is the wordplay.
'coordination with' indicates an anagram (coordination can mean organisation).
'european' becomes 'E' (abbreviation e.g. EU).
'losing' mixed up with 'e' can make 'SLOE-GIN'.
(Other definitions for sloe gin that I've seen before include "Legions (anag.)" , "Drink needed" , "tipple" , "Alcoholic infusion" , "Liqueur made with blackthorn fruit" .)
