The UK Parliament is both the House of Commons and the House of Lords and of course, the Sovereign. The UK Parliament is not only the House of Commons.
I do despair. All these people voted in the referendum to ‘make Parliament Sovereign’ and they don’t even know what Parliament is.
And then, after being so keen to ‘make Parliament Sovereign’, many of them seem desperate to exclude Parliament from the process of triggering Article 50 and determining our relationship with the EU going forward.
