Diolch, Llywydd. First Minister, I'm aware that the UK has donated the majority of any vaccines that are surplus to the UK, of course, to COVAX to support developing countries, but I understand something different to you, First Minister, in terms of World Trade Organization members' developing views on a proposed waiver of some of the provisions of the trade-related aspect of intellectual property rights agreement to tackle COVID-19. The UK Government, as I understand it, is actively engaging positively in that. But can I ask, First Minister, do you foresee any negative issues regarding waiving the patents of vaccinations, what are the unintended consequences of that, and how can these issues be overcome?
