My hon. Friend raises a very worrying issue. We are determined to put a stop to this new type of crime. The Home Office has been working closely with a number of partners, including the motorcycle and insurance industries and the police, to develop an action plan. We will review progress early in the new year.
On acid attacks, the Government are consulting on new legislation that would include the prohibition of the sale of harmful corrosive substances to under-18s, and the Home Secretary intends to put sulphuric acid on the list of regulated substances. It is a big challenge. I am sure that, like me, my hon. Friend is pleased that traditional crimes are decreasing, thanks to the excellent efforts of our law enforcers, but we must and will react quickly and effectively to modern crimes.
