What is considered the cornerstone of British life?

The concept of the rule of law is absolutely fundamental to understanding British society. It essentially means that everyone, including the government and those in power, is subject to and accountable under the law. This principle has evolved over centuries, with key milestones like the Magna Carta in 1215, which limited the power of the monarch and established the idea that even the king was not above the law. Over time, this evolved into a system of laws created by Parliament and interpreted by independent courts. The rule of law ensures fairness, stability, and predictability in society. It protects individual rights and freedoms, prevents arbitrary use of power, and allows businesses and individuals to operate with confidence. While attending church, supporting a local team, or participating in festivals are all part of British culture, they don't provide the essential framework for a fair and just society in the same way the rule of law does. Without the rule of law, these cultural activities could be suppressed or unfairly regulated.
Think of the 'rule of law' as the foundation upon which all other freedoms and rights are built in Britain.
