Old European turning up in Kyiv, also Guyana (8)
I believe the answer is:
yugoslav
'old european' is the definition.
(I've seen this before)
'turning up in kyiv also guyana' is the wordplay.
'turning up' says the letters should be written backwards.
'in' indicates the answer is hidden within the clue.
'valsoguy' is hidden within 'kyiv also guyana'.
'valsoguy' back-to-front is 'YUGOSLAV'.
(Other definitions for yugoslav that I've seen before include "from Croatia?" , "old Republican" , "Tito's nationality" , "Split with this person? Perhaps" , "Old East European" .)
