Is Kraken banned in the UK?

Excuse me, I'm a bit confused about the status of Kraken in the UK. Could you please clarify whether Kraken, the popular cryptocurrency exchange platform, is banned in the United Kingdom or not? I've heard conflicting information and I'm trying to get a definitive answer. If Kraken is indeed banned, could you also elaborate on the reasons behind the ban and any potential implications for UK-based cryptocurrency traders?
