Trade and Free Trade Agreements have been a topic of much public debate in the UK. After Brexit, the UK will sign its own free trade agreements, a competence that for decades has been exercised exclusively by the European Union. The government has proposed a Trade Bill as a first step towards signing the UK's first free trade agreements. The Public Bill Committee set up to scrutinize the Bill invited Dr Holger Hestermeyer, Shell Reader in International Dispute Resolution, to provide evidence to the Committee. 

In his evidence on 23 January 2018 Dr Hestermeyer answered a number of questions relating to EU Free Trade Agreements and the process and difficulties of copying such agreements, including agreements with Norway (the EEA), Turkey and Switzerland, for the UK. He emphasized the role of stakeholder involvement in the negotiations of free trade agreements and parliamentary scrutiny of free trade agreements, discussing scrutiny processes in other countries.

A number of academics of the law school have shared there expertise with parliamentary committees concerning the exit of the UK from the EU. Professor Takis Tridimas gave evidence at the House of Lords Financial Affairs Sub-Committee, Professor Satvinder Juss to the House of Commons Women & Equalities Select Committee, Dr Federico Ortino to the International Trade Committee, Professor Alex Turk to the Exiting the European Union Committee and Dr Hestermeyer has served as Specialist Advisor to the House of Lords EU External Affairs Sub-Committee.
