The noble Lord makes an important point, as did my noble friend. That is why I emphasised that through the Protect work we do, alongside our higher education providers, we already use the expertise of, for example, the National Protective Security Authority and the National Cyber Security Centre to work with our academic sector to make sure that we safeguard crucial intelligence and methods, even while we welcome international research collaborations, as well as the benefit that comes from international students. Any student who wanted to study, in this country, an area that could be exploited to support military programmes of concern would have to go through the vetting process outlined in the academic technology approval scheme. That does not mean that there is not more we can do, but we take this seriously, and we will continue to do that, to safeguard this country’s interests.
