S/L/11. "Under the largely unwritten constitution of the United Kingdom, the separation of powers is difficult to ascertain and evaluate."

There has been no major upheaval in the United Kingdoms recent history warranting a written constitution. An exception to this was a short interval of time when the Monarch was removed and powers were taken over by government. This caused the need to set a new organisational composition. A predominant division of functions is what ought to happen but in theory due to the early construction of the government, and the functions being held by more than one person, not allowing a pure separation.
