My understanding is that “soon” is the official word. It has been complicated by other things going on, and, of course, the clock is light, because we are expecting an election, without doubt.
I don't think this is an issue where there would be a great difference between whichever party is next in power. I think there is a certainly a question of resourcing, as well, against the background of some of the institutional changes we've had, given the changes in prime ministers and ministers, which has generally slowed down the process of creating things like this in a number of areas.
