I'm not OP but a quick yandex search (google isn't great for conservative news) suggests ~12k people were arrested last year for speech. https://nypost.com/2025/08/19/world-news/uk-free-speech-stru...
This article says 10k https://www.zerohedge.com/political/britains-speech-gulag-ex...
More broadly it's been a huge issue for a while, tons of articles come out of the UK for people being arrested for criticizing politicians/policies. Even more dystopian is it's hard to report on, because the police might come after you for talking about it. Germany is having similar issues, it's easy to forget most of the world (including Europe) doesn't have free speech
