Dividing work between the Commons, assembly and Lords

Why keep constituency and proportional representatives in separate houses, and how would the three chambers divide their work?

The proposal separates the chambers to avoid disputes over representatives' status: the Commons forms the government, the assembly checks spending and legislation, and the Lords handles specialist scrutiny.

The proposal keeps constituency and proportional representatives in separate chambers to avoid disputes over their relative status within one house. The Commons supplies the government and the assembly checks spending and ordinary legislation. The Lords concentrates on technical questions and bodies requiring specialist knowledge, so different categories of legislation pass through different pairs of chambers. Each house would have 400 members, making 1,200 parliamentarians in total.
