The authors regret an error in the abstract and introduction of the above article.

In the abstract, the following sentence:

“We empirically disentangle these relationships with a comprehensive dataset of 4.8 million Facebook posts by all active sitting MPs in all EU27 national parliaments plus the UK between 2018 and 2023, using large language models to identify protest-related posts and those that announce protest events.”

should read:

“We empirically disentangle these relationships with a comprehensive dataset of 4.2 million Facebook posts by all active sitting MPs in the EU27 national parliaments, excluding Croatia, plus the UK between 2018 and 2021, using large language models to identify protest-related posts and those that announce protest events.”

In the introduction, the following sentence:

“Our dataset comprises all posts of all members of the national parliaments from all EU countries and the UK who possessed an account between 2018 and 2023.”

should read:

“Our dataset comprises all posts of all members of the national parliaments from all EU countries, excluding Croatia, and the UK who possessed an account between 2018 and 2021.”

These statements have been corrected to reflect the data section in the paper.

The article has been corrected, and the authors apologise for the errors.
