The right hon. Gentleman is right to talk about managed risk. He will recognise that we have been managing the risk presented by Huawei’s specific circumstances within the 4G network for some considerable time. He is also right, of course, that we have to consider the potential delay to the roll-out caused by any measures we decide are necessary. I repeat that the most important criterion is that we act in our national security interest. If that causes delay, it may well still be the appropriate course of action, but we will need to decide that when we are in possession of all the facts. He has my assurance that when we do that we will make the most balanced judgment we can. As I said to my right hon. Friend John Redwood, all commercial operators will need to take account not just of what we have said today but of what they already know about the position in the United States and elsewhere.
