Grayling came under criticism as Shadow Home Secretary over the Conservative Party's use of statistics on violent crime. In February 2010, the Conservative Party issued press releases to every constituency in the UK claiming that crime had "risen sharply" in the UK. They failed, however, to take into account the more rigorous system for recording crime. The chairman of the UK Statistics Authority, Sir Michael Scholar, said that the figures Grayling was using were "likely to mislead the public" and "likely to damage public trust in official statistics" as the way in which crime was calculated had been changed in 2002.
