Abolish the Monorchy

Some people suggest that every law has to be unpicked, each one having references to the Crown or monarch removed and edited. That's not how this kind of change works. Since 1989 countless countries across Europe and elsewhere have made much bigger transitions from authoritarian regimes to democracies. They didn't rewrite or scrap every law that existed before they freed themselves from oppression.

Czechia, has managed this kind of transition twice, once when ditching communist rule as part of Czechoslovakia, and then when it separated from Slovakia just a couple of years later.

Barbados gives a neat example of how it works. In the legislation that introduced the republic, they said "any reference to the Queen ... shall be read and construed as if it were a reference to the State," and "any reference to Crown lands shall be read and construed as a reference to State lands," and so on. A single paragraph overwrites all references to Crown or monarch.

Where existing laws contradict a new constitution, the new constitution automatically overrides the law.

Britain is perfectly capable of drafting and agreeing a new constitution and changing to a republic.
