In short, yes. If memory serves me correctly, that point is explicitly made in the strategy document, both in general terms about the speed at which we move through phases and on some particular issues around public transport, for example, where we might require different approaches in different areas for obvious reasons. The evidence might, of course, lead us in that direction.
I have always said that we do not rule out that approach, although we have to balance it with issues of practicality, deliverability, ease of understanding and ability to communicate clear messages. So much of what we are dealing with just now involves difficult balancing acts. We will continue to strike that balance as best we can, and try not to rule anything out that might be helpful at some stage in what we are trying to achieve.
