I think I've mentioned on several occasions that we need at least two years. Two years back from 2019 brings us to 2017, as I have indicated. I rely on the commitment of the government to introduce and have legislation in place by, I believe, next spring. After June 2017, I think my successor will get very anxious and nervous about being able to conduct an election under a significantly changed system.
Again, there is still time, but the time is short, without a doubt.
