Berwick upon Tweed has been in Scotland and in England at various times. (It is now in England but plays football in the Scottish league).
There is an apocryphal story that Berwick is (or recently has been) officially at war with Russia. According to a story by George Hawthorne in The Guardian of 28 December 1966, the London correspondent of Pravda visited the Mayor of Berwick, Councillor Robert Knox, and the two made a mutual declaration of peace. Knox said "Please tell the Russian people through your newspaper that they can sleep peacefully in their beds." The same story, cited to the Associated Press, appeared in The Baltimore Sun of 17 December 1966; The Washington Post of 18 December 1966; and The Christian Science Monitor of 22 December 1966. At some point in time the real events seem to have been turned into a story of a "Soviet official" having signed a "peace treaty" with Mayor Knox; Knox's remark to the Pravda correspondent was preserved in this version.
The basis for such status was the claim that Berwick had changed hands several times, was traditionally regarded as a special, separate entity, and some proclamations referred to "England, Scotland and the town of Berwick-upon-Tweed". One such was the declaration of the Crimean War against Russia in 1853, which Queen Victoria supposedly signed as "Victoria, Queen of Great Britain, Ireland, Berwick-upon-Tweed and all British Dominions". When the Treaty of Paris was signed to conclude the war, "Berwick-upon-Tweed" was left out. This meant that, supposedly, one of Britain's smallest towns was officially at war with one of the world's largest powers – and the conflict extended by the lack of a peace treaty for over a century.
