Polls close in Istanbul re-run election seen as test for Erdogan

ISTANBUL, June 23 (Reuters) - Polls closed and votes were to be counted on Sunday in the re-run of Istanbul's mayoral election, which has become a referendum on Turkish President Tayyip Erdogan's policies and a test of Turkey's ailing democracy.

Initial ballot results were expected to be reported over the next few hours in Turkey's largest city.

In the first vote in March - the results of which were later scrapped - the opposition Republican People's Party (CHP) candidate secured a narrow victory over Erdogan's AK Party (AKP). (Reporting by Ebru Tuncay; Writing by Jonathan Spicer; Editing by Humeyra Pamuk)
