Reproduce shocking article about European power (9)
I believe the answer is:
replicate
'reproduce' is the definition.
(I know that replicate is a kind of reproduce)
'shocking article about european power' is the wordplay.
'shocking' indicates an anagram (letters shocked or shaken).
'about' is an insertion indicator.
'european' becomes 'e' (abbreviation e.g. EU).
'power' becomes 'p' (symbol in physics).
'article' with letters rearranged gives 'rlicate'.
'e'+'p'='ep'
'rlicate' placed around 'ep' is 'REPLICATE'.
(Other definitions for replicate that I've seen before include "Copy, reproduce" , "Copy exactly" , "Make an exact copy of" .)
