A further 12 peers would be elected by the entire United Kingdom, the six highest scoring losers from the smaller parties, and six Crossbenchers. I the latter case, again, each of us would vote for one candidate and the top six would be declared elected.
The price of this might be the abolition of the 92 elected hereditaries. There might also be calls for quotas for women and for ethnic minorities. In that event, or indeed otherwise, all should be required to come from the social categories C2DE, and those in all areas except London, though perhaps not in the national elections, to come from the most rural third, or possibly quarter, of wards in the area.
