I was once asked to do a walking tour of Croydon, my borough in London and also where the composer Samuel Coleridge Taylor lived for most of his life. He was a man of mixed heritage who studied music and composed the Hiawatha Wedding Feast inspired by Hiawatha, written by Henry Wadsworth Longfellow.

Unlike in the United States, where the Constitution was written down by the Founding Fathers nearly 250 years ago and is regarded as sacrosanct by many Americans, the British Constitution has never been formally inscribed but instead has evolved over centuries. The Supreme Court in Parliament Square can only decide if the government has acted within the law as it stands and cannot decide what that law should be. The Court does not have the power to overrule the politicians who sit in the Palace of Westminster opposite. Parliament always has the ultimate authority under the British system.
