*Daisy Anne* does not have a constitution that is contained in a written constitutional instrument
QED I think
The UK legal system works on case law and precedent. This is why it is so important that every departure from precedent by the current PM and the current Governmet is so momentous - they set a precedent to be referred to when in future leaders try departures even further from the UK ethos.
The UK has no FAT SINGLE PACKAGE containing a dated document labelled "Constitution". However, this does not mean it has no written constitution. It just means that various aspects of it are in different documents, depending on when and by whom they were created. Every law and court decision that has ever been made, ever since written records have existed, is there in black and white and is available for consultation. The rules that were laid down for a conastitutional monarch are there, as are the criminal and civil law and anything else that governs how the state and the individual interact. among other sources, Hansard records the proceedings in Parliament, and the records of trials record the legal points raised and the verdicts reached.
For instance, there is a full record of the decision of the Scottish Law Lords that Johnson was at fault for using a procedure to prorogue Parliament early to avoid further debate on the controversial Brexit Bill - which became an Act when he shortened the deadline for more talks on it. If anyone else tries that route to get their pet legislation through without due consideration by all of a free Parliament, that record is there to deter them.
Thus it is not only a snapshot of the machinery of state at one moment of time, but also a record of the discussions that went on in forming those laws and regulations, and the arguments behind the decisions.
