My hon. Friend is absolutely right to raise the issue of cyber-attacks. I caution, though, that cyber-attacks will not be prevented by removing Huawei equipment from the system. There are vulnerabilities across the network, and indeed one reason that we are introducing the telecoms security Bill is to start to address some of those. We have seen—it is in the public domain—that hostile Russian actors, for example, have already been able to attack our networks. With regard to the wider position on China, we need to have a full and frank relationship with China, and we have done that, but this announcement is principally about the US sanctions.
