421C's comments are spot on reference the scope of the briefing. When we first raised this with our authority they insisted that every non_UK examiner would have to be briefed at Gatwick. There was a portion of me that was hoping this would be carried out across Europe because I would have needed the 'grand tour' to visit the authorities that we examine for. I suspect that common sense will prevail in the end - the online system sounds sensible.
