Russell, you're correct—outdoor education can bring huge benefits to children and young people, and, as you said, in a range of developing skills and knowledge. At this time, day trips to such residential centres can indeed go ahead, and as long as schools do that in a risk-assessed way, there is no reason why all of those activities have to stop. But at this stage, scientific advice is very clear that residential trips are not appropriate. But as I said in my initial answer to you, we will continue to keep that under review, and we do not want to limit those residential trips for a moment longer than they need to be, given the benefits to children that you have outlined.
