Actress troubled about European Union cuts made by these (9)
I believe the answer is:
secateurs
'cuts made by these' is the definition.
(secateurs cut things)
'actress troubled about european union' is the wordplay.
'troubled' is an anagram indicator.
'about' means one lot of letters goes inside another.
'european union' becomes 'eu'.
'actress' with letters rearranged gives 'secatrs'.
'secatrs' enclosing 'eu' is 'SECATEURS'.
(Other definitions for secateurs that I've seen before include "They make cuts" , "Pruning tool" , "Small pruning shears" , "Gardener's tool" , "Clippers used for pruning plants" .)
