City in Czechoslovakia (4)

Ross

I believe the answer is:

oslo

'city' is the definition.
(capital of Norway)

'in czechoslovakia' is the wordplay.
'in' indicates a hidden word.
'OSLO' can be found hidden inside 'czechoslovakia'.

(Other definitions for oslo that I've seen before include "Solo in Norway?" , "Go solo to European capital" , "Former Christiania" , "Location" , "City in Norway" .)

I've seen this clue in the Newsday, The Mirror and The Telegraph.
