ISTANBUL (Reuters) - Voters in Istanbul will head back to the polls on Sunday to choose a mayor, after Turkey's election authority scrapped the results of a March vote in which President Tayyip Erdogan's ruling AK Party lost to the main opposition.
The rerun has ramifications far beyond city hall. Erdogan described the initial vote there and elsewhere in March as a "matter of survival" for Turkey.
