The first black irony of the PM's letter [to the Speaker of the House of Representatives and the President of the Senate] was that in a building full of lawmakers, the police have to write to those lawmakers to point out that if a crime has allegedly been committed, they need to either report it, or, if it is a matter like sexual assault, at least seek advice from the police about what to do about their knowledge a crime has allegedly been committed, if the complainant does not want to come forward. The second irony must be in the Prime Minister circulating this piece of information around the Parliament, given the long list of people in his own government, and his own office, who it appears had reason to suspect a serious crime may have been committed, but didn't say anything.
