For one year, parliament vacated in country (5)
I believe the answer is:
egypt
'country' is the definition.
(Egypt is a country)
'for one year parliament vacated' is the wordplay.
'for one' becomes 'eg' (both can mean 'for example').
'year' becomes 'y'.
'vacated' says to hollow out the word (remove centre letters) (internal letters vacate the word).
'parliament' with its centre removed is 'pt'.
'eg'+'y'+'pt'='EGYPT'
'in' is the link.
(Other definitions for egypt that I've seen before include "Cleopatra's country" , "Part of Africa" , "foreign country" , "Where M. Antony died" , "North African nation" .)
