A solution to the mass over population of the house of Lords is available right now with no new legislation required.
Euthanasia of peerages. Not (necessarily) euthanasia of peers, just of peerages. Set a size for the House of Lords and operate one in/one out. How the peer to be removed is selected doesn't really matter - as long as the new peer is more useful than the one leaving, the public win.
We can start right away - list all the peers, rate them, and terminate all but the top 200(?). If there is any dispute from the top losers they can debate to replace one of the top 200... Maybe put on TV and let the public vote them in/out.
Job done - could all be fixed by Christmas.
