Regional provider is owned by LetterOne, whose investors include Mikhail Fridman and Petr Aven
The UK government has ordered the Russian oligarch-backed investment company LetterOne to sell regional broadband provider Upp, saying its current ownership was a national security risk.
The business secretary, Grant Shapps, said the risk to national security relates to “the ownership of Upp … and Upp’s expanding full fibre broadband network”.
