I want to come back to some of the information that we've already heard.
Some time ago I did an Order Paper question and asked about the VRAB appeals in years 2014-15 and 2015-16.
In terms of percentages, in 2014-15 about 50% of the reviews were successful. That compares with 44.6% in 2015-16. In terms of appeals, in 2014-15 some 57% of the appeals were successful; then subsequently, only 34.7% of the appeals were successful. It's a significant drop, particularly in regard to the appeals.
I wonder whether you can comment on why the appeals are less successful now as compared with a year or two years ago.
