Although the UK will no longer be a member of the EU, the Withdrawal Agreement provides for a transition period up to 31 December 2020.
During this transition, EU rules and regulations will continue to apply to the UK and the UK will remain part of the EU's Single Market and Customs Union. There will be no immediate changes for citizens and businesses in their day-to-day dealings.
The European Commission has published a number of readiness notices offering advice to businesses and citizens across a range of sectors. Find the latest here.
