Llywydd, yes, we have produced such estimates. We published them alongside the final budget in December of last year. They showed, for example, that we anticipate landfill disposals tax to bring in £26 million in the current financial year, falling as that tax is intended to do to £20 million in the year 2021-22. Our forecasts are supplemented by the work of the Office for Budget Responsibility. They published updated forecasts for the two Welsh devolved taxes and Welsh rates of income tax in March of this year. They are broadly comparable with the figures that we produced in December, and both sets of figures will be available to the Finance Committee for them to scrutinise the actual performance of these taxes as that information becomes available during this year and beyond.
