This bill represents the culmination of efforts over many years, beginning under the last Government and carried forward by this one. It's an unusual bill, because most of its 300-plus pages are devoted to fleshing out the definition of secondary legislation in section 5 of the Legislation Act 2019. To explain the need for this, I will go briefly into some history. This will remind members why this area of law is in desperate need of reform and why the Regulations Review Committee recommended a serious overhaul in its report in 2014.
