Copy held in Czech office (4)

I believe the answer is:

echo

'copy' is the definition.
(echo can mean a copy or duplication)

'held in czech office' is the wordplay.
'held in' says the answer is hidden in the clue.
'ECHO' is hidden within 'czech office'.

(Other definitions for echo that I've seen before include "Close imitation" , "Noise heard again" , "letter we hear" , "Reflection of sound waves" , "Parrot" .)

I've seen this clue in The Sun.
