In the week the Netherlands goes to the polls, the irruption of Recep Tayyip Erdoğan into the Dutch election has wrenched the campaign out of its somnolence. At the weekend, the Turkish foreign minister, Mevlüt Çavuşoğlu, and the family minister, Fatma Betül Sayan Kaya, came to campaign among Netherlands-based Turks for next month’s plebiscite over extending President Erdoğan’s powers. The Dutch government banned Çavuşoğlu from entering the country and, after stopping Kaya entering the Turkish consulate in Rotterdam, kicked her out into Germany. Turkey has had a long-standing friendship with the Netherlands since Atatürk’s day. ‘Security’, that trusty standby for squelching political inconvenience, is cited as the reason for banning the ministers and their Rotterdam rally. Early on Sunday, police dispersed demonstrators with dogs and water cannon. Erdoğan has accused the Dutch government of Nazism.
