Under the rule of law, no one, including the Prime Minister and other politicians, is above the law. This means that all individuals are equally subject to the laws enacted by Parliament. However, general principles or unspoken rules that have not been formally incorporated into law cannot be enforced against individuals. Therefore, politicians, like any other citizens, must adhere to the laws as written. 

Key Point: The rule of law is a fundamental principle of the British constitution, ensuring that all individuals and authorities within the state, including the government, are bound by and accountable to the law. This principle upholds legal equality and prevents arbitrary exercise of power.
