Turkey's president is on a campaign blitz in a quest to secure sweeping new powers.

Recep Tayyip Erdogan travelled to the city of Canakkale to drum up support for a "yes" vote in next month's referendum. The president told tens of thousands of Turks why they need a new system of rule.

But despite strong support, there are still some who are not convinced by Erdogan's arguments.
