In December 1980, the "New Statesman" revealed the existence of secret tunnels linking government buildings, which they claimed would be used in the event of a national emergency. It is believed these tunnels also link to Buckingham Palace. Author Duncan Campbell discussed these facilities in more detail, in the book "War Plan UK: The Truth about Civil Defence in Britain" (1982). Peter Laurie wrote a book about these facilities, titled "Beneath the City Streets: A Private Inquiry into the Nuclear Preoccupations of Government" (1970).
