My hon. Friend raises an important point about the international benchmarks that we can look towards. In reaching conclusions on how to bring about a phased return of schools, we looked at how it had been done in countries such as Denmark, the Netherlands and many others. We will see a mirroring of the approach taken in Denmark here in the United Kingdom. That is the right approach, because we have not seen a negative impact as a result of schools starting to return in Denmark. That confirms that our approach is the right approach, and I certainly hope that trade unions in this country will speak to trade unions in Denmark.
