Top wise man's present in photo: Ivory Coast's borders breached in dubious triumph (7,7)
I believe the answer is:
pyrrhic victory
'dubious triumph' is the definition.
'top wise man's present in photo ivory coast's borders breached' is the wordplay.
'top' means to remove the first letter.
'wise man's present' becomes 'myrrh' (gold, frankincense and myrrh).
'in' is an insertion indicator.
'borders' suggests taking the first letters (I've seen 'border' mean this).
'breached' becomes 'victory' (I can't justify this - if you can you should believe this answer much more).
The first letters of 'photo ivory coasts' is 'pic'.
'myrrh' with its first letter removed is 'yrrh'.
'yrrh' placed into 'pic' is 'pyrrhic'.
'pyrrhic'+'victory'='PYRRHIC VICTORY'
'in' acts as a link.
Can you help me to learn more?
(Another definition for pyrrhic victory that I've seen is " A triumph but at too great a cost".)
