Glad to see the back of her

So much for Lianne Dalziel. But what cased the Prime Minister's sudden change of heart? The cynical view is that she focus-grouped it, and found that the public wanted a scalp. But a little deduction suggests another reason: that there was in fact hard evidence that Dalziel's story about how she had acquired the leaked documents was false (and that evidence could not be kept secret). In other words, a Guinea pig has bought down a Minister. Go Guinea pigs!
