My Lords, I refer to my interests in the register. The Blackett review into critical dependency on the GNSS was published in January 2018. What progress has been made on the review’s first recommendation that operators of this critical national infrastructure should report on how vulnerable their systems are to a failure or interruption of the GNSS network? The Cabinet Office was tasked with assessing our overall dependency on these systems. When will this be published, along with an action plan to remedy any weaknesses and the proposals for back-up systems called for by Oliver Dowden, then the Cabinet Office Minister?
