Is Kraken banned in UK?

I'm quite curious about the status of Kraken in the UK. I've heard some rumors that it might be banned there, but I'm not sure if that's true. Could you please clarify this matter for me? I've been thinking about investing in Kraken for some time now, but I'm hesitant to do so if it's not legal in the UK. Could you also provide me with any relevant information or resources that I could use to further understand the legality of Kraken in the UK? Thank you very much for your time and assistance.
