I don't know why any one every thinks or thought such stuff was shocking. They are just humans pushing what they can get. No different to anyone else. What's shocking is the lack of consequence.
If it was a mistake fair enough, but they are not just humans they are our public representatives and they should at the very least behave with the same ethos their political masters propose the rest of us should.
Hence why the Jeremy Hunt affair stinks so bad; they say one thing but do the other.
