Somewhat flippant answer: you were just imagining the UK being saner.
There's been a law since 2000 compelling suspects of crimes to divulge their encryption keys or go to jail, for example. The lack of speech protection isn't new.

The origin of the USA's prohibition against self-incrimination was people who were tortured into confessions and other forms of undermining their own freedom. The original logic for this right does not apply to divulging encryption keys. It's not clear what higher purpose is being served by allowing people under investigation to halt those investigations by using encryption: it's not like they can be tortured into revealing incorrect information inside the encrypted files.
