We use the same electoral system as the U.K. The British Labour Party uses all-women short lists. It's permissive legislation, so all parties are allowed to use this kind of party quota. Now up to 50% of the party's target seats or safe seats are set aside for women. The first time it was used, in 1997, there was a 100% increase in women elected.
