Brexit—key steps, concepts and timeline

By way of background, Practice Note: Brexit—exiting the EU under Article 50 [Archived] explains the operation of the withdrawal process under Article 50 of the Treaty on European Union and considers some of the key issues and the consequences arising in the context of the UK becoming the first EU Member State to withdraw its membership.

Our Brexit legislation tracker records the progress of UK legislation introduced as part of the legislative project associated with the UK’s withdrawal from the EU. Also see: Brexit legislation tracker 2017–19 [Archived], which tracked the progress of primary legislation introduced as part of the legislative preparation for the UK’s withdrawal from the EU during the 2017–19 Parliament.

From the point of its exit from the EU (31 January 2020), the UK’s relationship with the EU was governed by the Withdrawal Agreement, an international treaty negotiated by the UK and the EU during the withdrawal period, which was introduced to:

•
tie up the administrative and financial loose ends associated with the UK’s membership of the EU
•
protect the rights of UK and EU citizens living in each

EFPIA and Medicines for Europe call for suspension of UWWTD EPR scheme implementation

The European Federation of Pharmaceutical Industries and Associations (EFPIA) and Medicines for Europe and other organisations representing the cosmetics and pharmaceutical sectors have urged EU Ministers of Economy to ask the European Commission to ‘stop the clock’ on implementing the extended producer responsibility (EPR) scheme under Directive (EU) 2024/3019 (Urban Wastewater Treatment Directive, UWWTD). They state that the cost of upgrading wastewater treatment to remove micropollutants may be significantly higher than the Commission’s estimate of up to up to €1.4bn annually until 2045. They also raise concerns that the methodology used to allocate toxic load to sectors overstated the contribution of pharmaceuticals and cosmetics to urban wastewater pollution. They argue that limiting EPR obligations to those sectors is inconsistent with the polluter pays principle. In addition, they indicate that the directive could result in increased financial and administrative burdens, particularly for small and medium-sized enterprises, and note that fixed pricing mechanisms in the pharmaceutical sector may limit the ability to pass on additional compliance costs, with potential implications for medicine supply. They call for a pause in the EPR-related provisions and for a further science-based reassessment of the directive’s impact.

Commission adopts recommendation on diagnostic reference levels for medical radiation procedures

The European Commission has adopted Recommendation (Euratom/2026/403) on the establishment, review and use of diagnostic reference levels for radiodiagnostic examinations and interventional radiology procedures. Building on Directive 2013/59/Euratom (the Euratom Basic Safety Standards Directive), the recommendation sets out methodologies and good practices for establishing, maintaining and periodically reviewing national diagnostic reference level systems for the medical use of ionising radiation. The measure forms part of the Strategic Agenda for Medical Ionising Radiation Applications (SAMIRA) Action Plan, an EU initiative aimed at ensuring the safe, high quality and reliable use of radiological and nuclear technology in healthcare.

MHRA raids two premises seizing unlicensed weight loss medicines

The Medicines and Healthcare products Regulatory Agency (MHRA) has conducted raids on two premises in Lincolnshire and Nottinghamshire as part of an ongoing investigation into an organised criminal network involved in manufacturing unlicensed weight loss medicines. The Criminal Enforcement Unit (CEU), supported by Lincolnshire Police, Immigration Enforcement and Lincolnshire Trading Standards, seized almost 2,000 doses of unauthorised weight loss medicines awaiting dispatch to customers, alongside manufacturing equipment, suspected pharmaceutical ingredients, packaging and commercial vehicles. The premises searched comprised a farm near Sleaford and a residential address in Grantham, believed to have been used for manufacturing and distributing unlicensed weight loss medicines including retatrutide and tirzepatide, as well as peptide products. The operation follows a previous raid in October 2025 in which CEU officers dismantled what the MHRA described as the UK's first illicit weight loss medicine manufacturing facility in Northampton.
