>>which seems quite plain that the allegation made would be handled as rape in the UK too
True, however this would only be the case had she not already consented to sex already that evening, in the UK it would be a valid defense to say "we went to bed, she consented to sex, as it was a matter of minutes and we were still in bed together, I presumed consent was still in place".
The "equivalent" crime would have to be based on conditional consent (i.e. "I only consent if you wear a condom"), which isn't structured as rape in UK law.
Given the women are not pressing charges and there's no independent evidence (too late for tests, and SMS logs shows boasting of sex without any mention of rape) any prosecution is very unlikely, the UK CPS probably would not consder the case in the public interest to pursue, I don't think that English law would take it very far.
Don't get me wrong, it's quite possible Assange is a rapist, I can't say if he's definitely guilty, or definitely innocent, and under law that means you should be free, this is true for all crimes, it doesn't matter if you bugger sheep or are a serial killer, no evidence, not guilty. If you think you might be a victim of a crime then report as early as you can and consider how you can best preserve evidence.
