Favoured condition entered by European is provisional (7)
I believe the answer is:
interim
'provisional' is the definition.
(thesaurus)
'favoured condition entered by european' is the wordplay.
'favoured' becomes 'in' (I've seen this in other clues).
'condition' becomes 'trim' (I've seen this before**).
'entered by' is an insertion indicator (I've seen this in other clues).
'european' becomes 'e' (abbreviation e.g. EU).
'trim' going around 'e' is 'terim'.
'in'+'terim'='INTERIM'
'is' acts as a link.
(Other definitions for interim that I've seen before include ", I'm put in grave situation initially" , "An intervening period of time" , "acting" , "Temporary - provisional" , "Meantime - provisional" .)
