The police suggest that public order could be threatened if the meeting goes ahead. The Flemish far right Vlaams Belang earlier announced it would organise a "counter demonstration" if the meeting proceeded.
This is the second occasion that such a meeting is banned in Antwerp. Last time round the meeting was to be staged in a public space. Today the meeting was scheduled for a private location.
A similar meeting in the Limburg town of Genk too is contested by Bart De Wever's Flemish nationalist N-VA. There the local Christian democrat mayor has decided to let the meeting go ahead.
Earlier an N-VA lawmaker insisted that it was not suitable for Turkish leaders to campaign here. Turks go to the polls soon in a referendum that will install a presidential regime.
