Yes - exactly. You have to believe in this thing called "sovereignty" and the goodness of the Great BoJo.
The "Dissolution and Calling of Parliaments Bill" which repeals the Fixed Term Parliaments Act is about to be enacted with nobody much noticing. This reintroduces the Royal Prerogative to summon and dissolve parliaments, in effect giving back the Prime Minister the choice as to when to call an election. The Great Bojo has sneaked in a clause that says that a court "may not question" (a) the "exercise or purported exercise" of those powers, (b) "any decision or purported decision relating to those powers" or (c) "the limits or extent of those powers". So The Great BoJo can now make up the rules has he goes along without the Supreme Court being able to challenge him.
That strikes me as a very good example of "sovereignty" in action. In our weak, unwritten constitution it gives an unprincipled government with a large majority the power to adjust the law so that those in power can stay there, with no effective constraint. Now the EU, with the UK taking a leading role, devised rules which member states are suppose to comply with, which require separation of powers, in this case between the judiciary and the executive. You can see precisely why the Johnsonites wanted out. They wanted, and are now using, unconstrained power to change the system to their own advantage.
