London welcomed nearly 18million international visitors in the last 12 months, and this number is expected to increase.  Many visitors come to see the artwork and cultural artifacts at major museums like the British Museum, National Gallery and Natural History Museum.  Others are interested in exploring major attractions like the Tower of London, Palace of Westminster, Westminster Abbey, Buckingham Palace and Hampton Court Palace.  However, an increasing number are visiting London for international sporting and culture events.

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.
