My right hon. Friend raises the distinction between 4G, 3G and 5G. First, 5G is the new technology. It is the successor to 3G and 4G. Indeed, as he said to this House previously, the reality of the 5G network is that it is fundamentally different, and it is a recognition of that fundamental difference that we are imposing these rules in respect of 5G. Of course, over time, 5G will be the replacement network and then, in turn, 5G will be replaced by 6G and, in all of that, Huawei will be absent.
