There was a real basis for the claim in late 2011: major UK infrastructure assets had foreign investors or owners, and the government later said in Parliament that, although detailed ownership figures were not held, “much of the UK’s infrastructure is foreign owned.” The National Infrastructure Plan 2013 also listed substantial foreign investment in UK infrastructure, including full or partial ownership stakes in assets such as UK Power Networks, High Speed 1, Northumbrian Water, Thames Water, Wales & West Utilities, and Heathrow. However, the statement is too broad to treat as fully accurate: large parts of UK infrastructure were still publicly owned or publicly managed, including Britain’s railway through Network Rail and the road network through the Department for Transport/National Highways system. So the claim is directionally true about significant foreign involvement, but false or misleading if read as saying most or all UK infrastructure was foreign-owned.
