Unlucky incident where Mike in Russia given Putin's head (6)
I believe the answer is:
mishap
'unlucky incident' is the definition.
(I've seen this before)
'mike in russia given putin's head' is the wordplay.
'mike in russia given' becomes 'misha' (I can't explain this - if you can you should believe this answer much more).
'head' suggests taking the first letters.
The first letter of 'putin' is 'p'.
'misha'+'p'='MISHAP'
'where' is the link.
Can you help me to learn more?
(Other definitions for mishap that I've seen before include "Stroke of bad luck" , "Accident, something going wrong" , "Unfortunate minor accident" , "Unlucky development" , "Contretemps" .)
