Diolch yn fawr, Llywydd. Cabinet Secretary, yesterday, you spoke about, and indeed your party voted in favour of, a tax on non-reusable and non-recyclable plastics in Wales. I wonder if you can now provide us with some clarification on the details and practicalities of this intention and how you might take it forward, or was it just a vague reassurance to Plaid Cymru that they have some continuing relevance in Welsh Government decision making?
