My hon. Friend speaks with experience and is absolutely right to ask that question. The door in question should have had resistance for 30 minutes. It must be tested against and meet the British standard, BS 476-22. There is a testing centre for such products, and testing centres must be accredited by the United Kingdom Accreditation Service. I do not want to make any judgments on what happened in this case, because it is subject to a live police investigation. The police have said that they are getting full co-operation from the manufacturer. It would be wrong of me to get into that, but I reassure my hon. Friend that the police are doing their work with that particular door and doors of that type, and we are doing the much wider necessary testing.
