I say to the Minister that a mixture of good and bad is not diversity. That is the first thing. He says that he puts the security of the nation first. In pursuit of that, the Government have claimed that there is no back door to Huawei hardware. The Americans assert differently. The Germans agree with them. Other countries agree with them. He served on the Bill Committee for the Investigatory Powers Act 2016. I remind him of sections 252 and 253, which give us the right to have a back door. How can we have a back door, when the hardware installer, the hardware supplier and the hardware administrator does not?
