Very latest (2-2-3-6)
I believe the answer is:
up-to-the-minute
'very latest' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for up-to-the-minute that I've seen before include "Current" , "Right now" , "Tie up the mount? (anag)" , "Incorporating the very latest developments" , "Extremely modern" .)
