Finally we have a European country doing what I've always called for.
Stop foreign funding of mosques and disallow entry to preachers from those countries who are prone to incite followers.

All mosques should be local. The local or national Islamic body of the country should be the only ones who build, manage, instruct and guide these mosques.

This is what is practised here in the Far East, even in Muslim countries like Malaysia and Indonesia. Singapore strictly enforces this.
What happens thus, is that the message in every mosque is uniformed. Preachers and sermons reflect the context of the religion in the country not those in other countries.

The major problem in having foreign embassies or bodies building mosques is that these bodies inevitably will bring the context of the religion from their own countries to the host nation.
Worse it also brings the rivalries from these countries to the host.

So if Turkish mosque is built, it's preachers will preach against say countries Turkey are odds with, say Syria or against the Kurds. A Qatari mosque inevitably will be rivals with a Saudi or UAE mosque.

And preachers from Muslim countries which adhere to a more conservative line will lament and rail against the liberalism in Western countries. This inevitably will see some of it's adherents taking it a step too far and slowly a chasm forms between them and their European hosts who will be considered un-Islamic.

If Muslims feel more comfortable with the stricter codes in conservative countries, by all means they should go there. But we cannot bring these countries stricter code here which is presently the case.

Britain should follow suit. Have a National Islamic body to run, educate and enforce the religion here. All outsiders have no say. They can be invited to give talks and lessons but under a strict formula issued by the British body not anything they choose. Comply and they can come again and again. Disobey and a deportation and long term ban issued.
