She gives bribe to ambassador holding information (6)
I believe the answer is:
sophie
'she' is the definition.
(I've seen this before)
'bribe to ambassador holding information' is the wordplay.
'bribe' becomes 'sop' (sop can mean a concession or bribe).
'to ambassador' becomes 'he' (His or Her Excellency).
'holding' is an insertion indicator.
'information' becomes 'i' (common abbreviation for information).
'he' placed around 'i' is 'hie'.
'sop'+'hie'='SOPHIE'
'gives' is the link.
(Other definitions for sophie that I've seen before include "Girl's name" , "--'s Choice, novel by William Styron" , "Hope is confused for this girl" , "Dahl perhaps" .)
