A better voting system

There has been much discussion of voting systems in the past and given the current state of the parties there will be a lot more after the general election. So here is a simplistic proposal.

In each constituency the will be an alternative vote, that is each elector lists the candidates in order and the votes get transferred until one candidate has a majority. This will elect the lower house. The upper house will be chosen by proportional representation based on the first votes of each elector.

To avoid to many small parties there would be a limit that for a party to count towards the upper house they would need at least 10% of the national vote.

To ensure that the constituency MP's were genuinely representative they would need to have been resident in the constituency for at least 5 continuous years before the election. Residency for a year would mean having spent at least 250 nights in the years in the constituency. An almost simple rule but it would stop rich carpetbaggers just buying a house in an area and never living there. It would also mean tha the lower house would have to organise its affairs much more efficiently, it could only meet for 115 days a year! Given that many MP's seem to think it is only a part-time job what would be the problem with that. I am sure some would resent that argument that it is aprt-time but if an MP can be a minister as well as an MP, both jobs must be part-time.

Also ministers would have to come from the upper house or work from home. Wouldn't that set a good example.
