"If you are going to make such a claim then you need to provide a damn sound and well supported argument."

No I do not.
I offer it as a plausible theory, and it is not my own.
It has been put forward by two Labour politicians, one very senior, both of whom have worked for years with the Pakistani communities they represent, and are supported and respected by those communities.

It works like this.
I put up my theory and you should try to find fault and/or an alternative.
Just calling me names is not the way.
