@ boogers, we have a two-house parliament in Westminister already with a top-heavy house of lords which costs a fortune.
The House of Lords costs ~£100 million a year. This is small change.
The PM floods the House of Lords with his cronies like Ruth Davidson being one costing a fortune. A good place to have a nap and get paid for it.
There are currently 242 Tory Lords. There are 530 other Lords.
There's a good case to be made that the HoL is too large, but it's certainly not stuffed with Tories.
You forget boogers that the members of the Scottish Parliament are elected by the people. The House of Lords are placed there by the PM and I would think at present there will be a big tory majority.
Good try but until the House of Lords are put there by election it is obviously going to be flooded by Tory members.
The Scottish Parliament is unicameral legislature, and as such should be compared to the House of Commons.
Most people agree that a bicameral legislature has significant advantages over a unicameral legislature, and there's strong debate over whether a directly elected second chamber is better or worse than other mechanisms. The House of Lords actually does pretty good work when it comes down to the important thing: scrutinising legislation.
