The UK has the Magna Carta http://www.bl.uk/magna-carta/articles/magna-carta-english-translation
... and just like the US Constitution, it has been amended over the years, however, it still remains the guiding document for the UK
The Magna Carta (1215) was just the first document. A better description compared to the US is that it was more like the Declaration of Independence, instead of the US constitution, in that it was not a particularly organizational document, but a protest against and set limitations on the king.
Some refer to the Provisions of Oxford (1258) as the first written constitution, in that it was much more organizational in character.
But in either case, the Bill of Rights (1689), followed by the Act of Settlement (1701), and subsequent acts, were comprehensive as organizational documents, so have had much greater impact.
Things really picked up steam only in the 20th Century.

Still, the lack of clarity in having a multiple source organization based in competing documents was a big impulse to the US founding fathers to have a single, comprehensive document as both the organizational guide of government, and a Bill of Rights to emphasize the limitations of government. It still took them two tries.
Israel hasn’t been around for very long, so still has much formative work to do.
