I count 50 leaving country (5)
I believe the answer is:
italy
'country' is the definition.
(Italy is an example)
'i count 50 leaving' is the wordplay.
'count' becomes 'tally' (tallying is a kind of counting).
'50' becomes 'L' (Roman numeral).
'leaving' suggests deleting specific letters.
'tally' with 'l' removed is 'taly'.
'i'+'taly'='ITALY'
(Other definitions for italy that I've seen before include "Original member of the European Economic Community" , "Barolo wine from here" , "Problematical (informal)" , "Country of southern Europe" , "Founder member of the EEC" .)
