Kiss a former official (5)
I believe the answer is:
pasha
'former official' is the definition.
'pasha' can be an answer for 'official' (I have seen 'Turkish official' mean 'pasha' so perhaps 'official' could also mean 'pasha'). I am not sure about the 'former' bit.
'kiss a' is the wordplay.
'kiss' becomes 'pash' (I can't justify this - if you can you should give a lot more credence to this answer).
'pash'+'a'='PASHA'
Can you help me to learn more?
(Other definitions for pasha that I've seen before include "High ranking Turkish official or officer" , "High-ranking Turkish officer" , "Former provincial governor in Egypt" , "Ottoman governor" , "Muslim dignitary" .)
