The Government’s ‘5G Supply Chain Diversification Strategy’ provides an overview of the Government’s intentions for addressing the current lack of vendors in the UK’s 5G infrastructure equipment market. The Government itself acknowledges that this will take time. Although the decision to forbid the use of 5G equipment procured from Huawei after 2020 was made following US sanctions announced in May 2020, the potential threat from telecommunications infrastructure supplied by foreign vendors and the concentration in the UK’s vendor market have been known for many years. It is therefore disappointing that the Government and its predecessors have not already developed and started implementing a strategy for diversifying the UK’s telecommunications infrastructure supply chain. Given the scale of the challenge and the urgency of the threat, the Government should publish, within three months, a more detailed action plan for implementing its diversification strategy. This should include a breakdown of how the initial budget will be spent and a series of milestones with target dates for completion.
