Where Soviet leader appeared in a fur coat (5)

I believe the answer is:
minsk
'where soviet leader appeared' is the definition.
The answer is a location as well as being a singular noun. This is suggested by the definition.
'in a fur coat' is the wordplay.
'in' is an insertion indicator.
'a fur' becomes 'mink' (mink is a kind of fur).
'coat' becomes 's' (I can't justify this - if you can you should give a lot more credence to this answer).
'mink' enclosing 's' is 'MINSK'.
Can you help me to learn more?
(Other definitions for minsk that I've seen before include "capital city" , "City of Belarus" , "Capital of Belarus" , "E European capital" , "Russian city" .)
