It is over two years ago that Theresa May, then the home secretary, announced that she would set up the great child abuse inquiry.

First, it was to be the Butler-Sloss Inquiry, but Lady Butler-Sloss resigned almost immediately because some objected to the fact that her brother had been Attorney General in the Eighties (“establishment cover-up”).

Then, for a few weeks, it was the Woolf Inquiry, but Fiona Woolf resigned because she admitted to having dinner with Lord Brittan, against whom lurid child abuse allegations had been made (“establishment conspiracy”).
