Thank you for your answer, Trefnydd. You've previously talked about, and your predecessors have talked about, reforming the business rate system in Wales. When it comes to business full rate relief, properties, of course, with a rateable value of up to £12,000 can benefit from rate relief in England, but in Wales that figure is just for business properties with a rateable value of up to £6,000. Can I ask you to provide an update on what progress is being made with regard to the work on reforming business rate with regard to supporting small and medium-sized businesses, so that when it comes to the rateable value they are on an equal footing and not disadvantaged because their businesses are located in Wales rather than over the border in England?
