Second House

Not the sort by the seaside, and but the one in Westminster. Why are we talking about a second elected chamber that is just going to end up with party placement and professional politicians like the lower house? After 15 years you are really going to have forgotten what real life is like.
Why not go back to a much older idea and have 200 members chosen for 6 months or a year by lottery? No arguments then about over or under representation. And a short period is long enough for then to remember who they are and not become assimilated into the system.
