The Retained EU Law (Revocation and Reform) Bill, which was only introduced in September of last year, has been an unmitigated disaster—designed to remove all remaining retained EU law from the UK statute book by the tenth anniversary of the Brexit referendum at the very latest. The Bill introduces a sunset clause, whereby the majority of retained EU law—thousands of pieces of legislation—will be automatically disapplied after 31 December 2023, unless it's otherwise preserved as assimilated law. 

On 18 November, the independent Regulatory Policy Committee issued its view that the Bill's impact assessment is not fit for purpose. The committee rated aspects of the impact assessment, such as its rationale and the cost-benefit analysis, as either 'weak' or 'very weak'. In early January, the Department for Business, Energy and Industrial Strategy admitted it had spent £600,000 on staffing costs alone in just two months as part of its review of the Bill, despite holding responsibility for only 318 pieces of retained EU law.

In light of this brief snapshot of the cost to the UK Government of this ill-thought-out Bill, what is the Welsh Government's current estimate of the resource demands, both in terms of cost and staffing, arising from the ongoing review of Welsh-specific retained EU law?
