Remove others accepting European Commission (6)
I believe the answer is:
resect
'remove' is the definition.
(to resect is to surgically remove)
'others accepting european commission' is the wordplay.
'others' becomes 'rest' (I've seen this before).
'accepting' is an insertion indicator.
'european commission' becomes 'ec'.
'rest' placed around 'ec' is 'RESECT'.
(Other definitions for resect that I've seen before include "Cut out tissue or part of an organ" , "Surgically remove a part of a structure or organ" , "Cut away or remove a bit of the body" , "Excise" .)
