This is a largely mechanical result of the proposed electoral system : proportional by region, as for the European parliamentary elections. We can extrapolate the last result, that of 2009, to get an idea. There are 5 parties representing the UK in the EU: by size of group, Conservative, Labour, Ukip, Libdem, Green. There might be one or two more parties represented because of the smaller quota required (120 "lords" per election, compared to 72 EMPs), but you get the idea.

This is sufficiently different from the FPP Commons method to be a pretty good way to elect an upper house. But cut the "life senztors" crap please.
