Okay.
We have one of the worst contexts in which to introduce a proportional system.
I will suggest a solution that was submitted to me by a researcher from France called the “mixed equitable majority” voting method. It is a proportional system in which the existing electoral districts are maintained. Compensation is achieved by changing the weight of the votes. Each vote for each party is given more or less weight in order to achieve proportional representation. It is used in Switzerland for the reason mentioned earlier. Someone had gone to court complaining that the system in force did not work. It is used in Zurich and in two Swiss cantons. I have done a few simulations but have not yet studied it in detail. It is challenging working with algorithms, I have to say. I have them, but I have not used them yet.
