Staff put out over EU scheme (9)
I believe the answer is:
manoeuvre
'scheme' is the definition.
(thesaurus)
'staff put out over eu' is the wordplay.
'staff' becomes 'man' (manning is a kind of staffing).
'put out' is an anagram indicator.
'over'+'eu'='overeu'
'overeu' with letters rearranged gives 'oeuvre'.
'man'+'oeuvre'='MANOEUVRE'
(Other definitions for manoeuvre that I've seen before include "See 16" , "Carefully contrived scheme" , "plan" , "A co-ordinated movement" , "Work on possibly private" .)
