On clause 5, you already have powers to amend ineffective retained EU law under section 8 of the European Union (Withdrawal) Act 2018, so you can make regulations under Henry VIII powers to deal with any deficiencies in retained EU law and social security. You have given yourself additional powers under section 13 of the European Union (Withdrawal Agreement) Act 2020 to make regulations for social security co-ordination, so you already have two sets of Henry VIII powers. You are currently negotiating a third social security treaty, annexed to the draft free trade agreement. If that is agreed with the EU, you will have another Act of Parliament that you will need to implement that. Why do you need a fourth set in clause 5? If there is anything left in social security law that you have not covered under the array of Henry VIII powers that you are arming yourselves with, primary legislation and the scrutiny of MPs in this room at the highest level is required.
