Snowden: UK government now leaking documents about itself

Information once leaked has a tendency to keep leaking, and it's been around a year since the first leaks were made. That's long enough for... um... leaks to appear in the small network of people who had access to the original leaked material.
I'm not trying to dismiss Greenwald's hypothesis, I think it's completely valid and better suits my conspiracy theorist ideals, but I think it's worth looking into the alternative that this info just got re-leaked to a less responsible journalistic channel.
But I sort of worry that GCHQ are actually naive enough to think that side-leaks (diversionary leaks? dummy leaks?) like this would be immediately accepted and not challenged by others.
