Wedding VIP (4,3)
I believe the answer is:
best man
'wedding vip' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for best man that I've seen before include "Key union facilitator r" , "The groom's assistant at a wedding" , "The groom's right-hand supporter" , "Bridegroom's mate" , "Groom's friend" .)
