And to be clear, the UK constitution is really the combined law passed over centuries (including the Magna Carts). There is no single, “sacred” document as in the US (which isn’t really sacred in practice - we can amend it or let SCOTUS re-interpret it).

The biggest difference between the UK and other constitutional countries is that parliament power is pretty much absolute and it is not bound by any document or pre-existing law.

In theory at least. In practice the courts have hinted that there are limits even for the parliament, and if it were to overstep some unwritten rules, it would cause a constitutional crisis.

Boris Johnson asking the Queen to prorogue parliament during Brexit debates is a solid recent example.
