Erdogan held a surprise rally on the streets of Istanbul on Saturday. During this 40th and last rally of this campaign, the Turkish president once again wanted to crush his social democratic opponent.

The vote may well turn into a referendum for or against the outgoing president, writes Caroline Baudry, editing by Alexandre Dalifard, on the eve of the presidential elections. The election will take place on Sunday.
