These Regulations update cross-references to EU legislation in social security legislation in advance of exit day. This ensures those cross-references are up to date at exit day and ensure those cross-references will capture any amendments to the EU legislation before exit day and, to the extent that they apply to the United Kingdom, any amendments to EU legislation made after exit day.
