Interesting use by the author of the phrase “We the People”.
There’s only one country on the planet where “We the People” are the sovereign, and it is not Her Britannic Majesty’s Green and Pleasant Land, where the sovereign is the Crown in Parliament which can do as it damn well pleases.
While the term "We the People" is uniquely American, the concept of the whole people as the sovereign is not. In fact, our very own T Jefferson helped write the core foundational document of the French constitution:
https://en.wikipedia.org/wiki/Declaration_of_the_Rights_of_the_Man_and_of_the_Citizen_of_1789
France is now - since 1958 - on its 5th republic, but the preamble is still referenced:
https://en.wikisource.org/wiki/Constitution_of_the_Fifth_French_Republic_(original_text)
The French people solemnly proclaim their attachment to the Rights of man and to the principles of national sovereignty as defined by the Declaration of 1789, confirmed and completed by the Preamble to the Constitution of 1946. By virtue of these principles and of that of the free determination of peoples, the Republic offers to those Overseas territories which express a desire to accept membership of them new institutions founded on the common ideal of liberty, equality and fraternity and conceived with a view to their democratic evolution.

We should all note that the essential claim made by the US, France and other democratic republics, is that government is created solely for the benefit of the governed. When it fails to provide equal protection of civil rights, it is not only the right, but the DUTY, for the people to alter **their** government. The UK is treading in dangerous territory here, because it would be perfectly legitimate for the military and/or people to rise up and overthrow the existing regime that is failing in these duties.
