What the Prime Minister is setting out today is his five-year plan for tackling extremism which he believes leads to terrorism.

It's a speech in which he'll set out very little in the way of new legislation but a lot as a far as his thinking is concerned about British Muslims who hold "intolerant ideas".

He will try to de-glamorise the appeal of fighting for brutal groups like the self-named Islamic State (IS) or ISIL.

They will strap bombs to you and kill you, he will tell men who are tempted to fly to Syria.

They will enslave you and abuse you, he will tell women who also have the urge to join IS.

And as the government prepares for a Commons vote in the Autumn to authorise air strikes over Syria, David Cameron will argue that Islamic terrorism was happening before the US and UK military conflicts in Iraq and Afghanistan.

His aides say Mr Cameron has for some time been alarmed by the intolerance with which extremist views has been met in some communities.

That is the kind of non-violent rhetoric which the Prime Minister believes can lead to terrorism.

He has previously upset some Muslims by claiming those views are 'quietly condoned' in certain communities.

They'll also be warnings about the lack of segregation in some areas and in some schools where 9 out of 10 pupils come from just one ethnic community.

And plans for police to confiscate passports if parents believe their son or daughter is planning to travel to Syria to join IS

It's difficult to see quite how Mr Cameron's strategy will be judged.

A terrorist attack which 'succeeds' is much more visible than a terrorist as attack which has been thwarted.

But given this strategy relies on the support and engagement of the communities to which he is directing these comments, success - initially at least - will depend on how they react to what he has to say.
