What's great about this is that instead of covering up the issue, Henry's behaviour has caused it to blow up and become way more visible. I certainly hadn't heard about any of this until reading OP.
True, but it's kind of a shame we're dependent on those emails being leaked. If they hadn't been then it'd be Dennis' claim that someone in the government pressured his employer to get him sacked. Which doesn't hold a great deal of weight and could easily be dismissed by a government keen to cover its ass.
