Deputy Minister, earlier this week, I met with pupils from St Aidan's Church in Wales School in Wiston just outside Haverfordwest in my constituency, which has set up a petition to ban single-use plastic milk bottles in schools across Wales. I'm sure you'll agree with me that it's great to see children and young people engaging with our petitions process and taking action on some of our biggest issues. In the circumstances, what support can the Welsh Government offer to the pupils of St Aidan's Church in Wales School, and what discussions have you had specifically with local authorities about banning single-use plastic milk bottles in schools across Wales?
