Should the UK rejoin PEM?

Whenever the topic of the Trade and Cooperation Agreement (TCA) review comes up, the Pan-European Mediterranean (PEM) origin cumulation zone is one of the topics mentioned as potentially in scope. Recently, several reports and organizations have included rejoining PEM as one of the recommendations for the new Government. Rejoining PEM is indeed one of the steps that could improve market access for products from all industries that could be done within the current format of the TCA. It could also be done without changing the essential character of the relationships, i.e. one based on a simple and fairly basic trade agreement.
