There was a presentation given by our NB recently, on the changes brought in by that EU document. The de-designation of 5 NBs was mentioned - it might be that their scope was reduced rather than being totally stopped.
The suggestion was that it was some of the 'smaller' continental based NBs, with just a handful of employees. It seemed to be suggested that small NBs will not be able to cope with the changes - particularly with things like unannounced audits.
That is all a bit vague, I'm afraid but details were not given.
