Look at father and important financial figures close to agreeing - amazing! (3-7)
I believe the answer is:
eye-popping
'amazing' is the definition.
(both can mean spectacular or shocking)
'look at father and important financial figures close to agreeing' is the wordplay.
'look at' becomes 'eye' (I've seen this before).
'father' becomes 'pop' (pop is a kind of father).
'and' says to put letters next to each other.
'important financial figures' becomes 'PIN' (personal identification number).
'close to' indicates one should take the final letters (the 'close' to the word).
The last letter of 'agreeing' is 'g'.
'eye'+'pop'+'pin'+'g'='EYE-POPPING'
(Another definition for eye-popping that I've seen is " Astonishing".)
