Turkish Foreign Minister Mevlut Cavusoglu on Tuesday said he would go ahead with a planned visit to Germany despite local authorities banning him from making a speech on safety grounds.

The comments came amid a row over the stopping of events in Germany meant to boost support for a vote in April that would increase President Recep Tayyip Erdogan's powers.

"I am going to Hamburg today," Cavusoglu told foreign countries' chief consuls, including Germany's, in Istanbul. "I will meet this evening with our citizens in Hamburg."
