That is relevant, as the Scottish model shows that, even in the Westminster tradition, changes can be made toward a moderate proportional voting system. I don't think anyone here would want our system to become extreme.
It's interesting that you say we should not take a recommendation at random and that everything forms a whole with interrelated effects. Of course, there is a lot of uncertainly, but there are also many international examples of how this has been done for decades.
At last year's Canadian election, we saw that the largest percentage of women in history were elected to the House of Commons. I say, well done. However, the women accounted for only 26% of MPs. At the current rate, based on the 2011 and 2015 elections, we will achieve gender parity in Parliament when my baby girl gets her old age pension.
What would you like to do to increase the role of women in Parliament more quickly?
