My hon. Friend makes the point about the seven-year cycle. If this goes ahead, are we committing ourselves to Huawei being the dominant force in this industry? We have had 3G and 4G, we are now on to 5G, and there will doubtless be 6G and 7G in time to come, but there will be no western ability to advance this software in the future because Huawei, through cut-price credit deals, will have crowded out the competition in perpetuity. That has to be dangerous.
