Public law help! Watch
That it isn’t settled and that it always is changing.
Assess whether the UK constitution is in flux by reference to ONE of the constitutional principles
URGENT HELP THANK U
So to answer the question you would need to pick one and assess how it has changed over time. For Parliamentary sovereignty you could talk about devolution, the EU, the fact we've had quite a few referendums to decide issues (Devolution, Scottish Independence, voting system, EU membership). For Rule of Law you could talk about the Human Rights Act and Judicial Review. For the Separation of powers you could discuss the new Supreme Court. And so on and so forth.
