The Ministry of Defence’s open and country-agnostic approach to foreign involvement means that the defence supply chain has been open to potentially hostile foreign involvement, with reports of companies being owned and influenced by foreign Governments whose values and behaviours are at odds with our own and who are known to engage in intellectual property theft. The Ministry of Defence should publish a list of countries it Foreign Involvement in the Defence Supply Chain 31 considers friendly and from whom investment should be encouraged. All those countries falling outside of this list should be barred from investing in the UK’s defence supply chain, including China and Russia.
