News agency attached to Echo and Mirror (3)
I believe the answer is:
ape
'mirror' is the definition.
(both can mean to imitate or copy)
'news agency attached to echo' is the wordplay.
'news agency' becomes 'ap' ().
'attached to' means one lot of letters go next to another.
'echo' becomes 'e' (phonetic alphabet: alpha, bravo, charlie etc.).
'ap'+'e'='APE'
'and' is the link.
(Other definitions for ape that I've seen before include "Imitate uncritically" , "Idiot" , "Anthropoid primate" , "Wild animal" , "Take off" .)
