You know when the political class has lost the plot when it starts to talk about reform of the House of Lords without taking into consideration the other constitutional events which have happened over the past decade.
We now have different powers for three "parliaments" representing Scotland, Wales and Northern Ireland. We do not have a parliament of any form for England.
Four lower parliaments with equal powers would be united under an elected Senate (replacing the House of Lords) which would bind in the four countries of the UK.
