As we are reaching the end of yet another challenging year, we would like to present you the European Law Blog’s top ten most-read blog posts of 2021. This list of top ten provides us with the opportunity to celebrate the most popular blog posts, to offer an insight into the topics that have gotten the most attention from our readers this past year, and to thank all of the authors who have contributed to our blog in these exceptional circumstances.

While posts on artificial intelligence and data transfers remain highly topical issues, our top ten nevertheless cover a variety of topics. Brexit is still a prominent topic amongst our readership, in particular issues related to the EU-UK Trade and Cooperation Agreement which was signed at the very end of 2020. The ongoing tensions between the EU and some Member States over the primacy of EU law have fostered much debate, it therefore comes as no surprise that in particular the recent decision of Poland’s Constitutional Tribunal has caught the attention of our readers.

Without further ado, here are our top ten most-read posts of 2021:
