With respect to the processing times overall, we try to do spousal applications within the service standard of 12 months, and unfortunately we're above that in 80% of the cases we're dealing with. Our global average at the moment is about 17 months. We continue to try to work our way through that.
The processing times are longer for a whole variety of reasons. The issue of marriages of convenience is a factor, but it's one among many factors that would be influencing this. I think it would be very difficult to isolate that as a key piece of this.
