I'm pleased to hear what the First Minister has said. Of course, there is an economic question here too, because, although there are planning and environmental implications, what we have seen is an explosion in the number of units of this kind that have developed across Wales. We may not be far off the point where we are over-producing. And while it is right that we encourage farmers to diversify, we must ensure that any growth that we see in the sector is sustainable growth. So, may I ask what assessment the Government has made of the sustainability of this substantial and sudden growth in this sector, and what is your intention in terms of encouraging farmers to diversify in directions that bring the most benefits to the rural economy but also benefits that will continue for many years to come?
