I am grateful to my hon. Friend for his generosity in giving way. Given that my experience is very recent, hon. Members will forgive me if I am not entirely accurate about the current rules. Last year, there was an attempted break-in at my office, and I asked the Independent Parliamentary Standards Authority whether it would cover CCTV. It refused to do so. When the same office was vandalised with threatening messages, I asked for guidance from the police and counter-terrorism officers, who both said there should be CCTV. However, IPSA continues to refuse to cover it. What does my hon. Friend think about that?
