The foreign investigation reproduced in Vogue (6)
I believe the answer is:
latest
'in vogue' is the definition.
(I've seen this before)
'the foreign investigation' is the wordplay.
'the foreign' becomes 'la'.
'investigation' becomes 'test'.
'la'+'test'='LATEST'
'reproduced' acts as a link.
I am not very happy about this link. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for latest that I've seen before include "Brand new, just out" , "Most up to the minute" , "In vogue" , "most behind time" , "delayed more than all others" .)
