The UK Parliament once again enjoys full legal sovereignty
Factortame Case
Prior to Brexit, EU law had 'primacy' over UK law. The UK Parliament could not introduce a law that conflicted with EU law, but now it can.
Political sovereignty
Not fixed and is restricted by parliamentary assertion
A party with a thin or non-existent majority
Will find it much more difficult to control the parliamentary agenda
Spring and autumn 2019
Parliament voted to take over the agenda of Parliament using Standing Order 24, wresting it away from government and allowing it to initiate its own votes on Brexit
If the popular will is divided, as shown by the EU referendum and also by the 2017 general election
The net effect is to empower ordinary MPS who hold more power in a hung parliament, thus allowing Parliament to take control of decision making
Despite devolution, Parliament retains reserved powers, and still takes the major decisions affecting the nation
The Sewel Convention is not legally binding and so the devolved bodies can be ignored by Parliament
Supreme Court ruled in 2017
The devolved bodies could not reject what Parliament passes in relation to Brexit
