It is crucial that the Government is equipped to make all the necessary corrections to the statute book before we leave the EU to ensure a smooth and orderly withdrawal. To achieve this, the power to enable this correction will need to allow changes to be made to the full body of EU-derived law. This will necessarily include existing primary as well as secondary legislation which implements our EU obligations, as well as directly applicable EU law which will be converted into domestic law once we leave. It will also include the power to transfer to UK bodies or ministers powers that are contained in EU-derived law and which are currently exercised by EU bodies. This does mean that the power will be wide in terms of the legislation to which it can be used to make changes.
