I am just catching up with these fascinating documents, each of them released by various Departments. Essentially they are the briefing papers for incoming Ministers so they can understand the structure of their new brief. Unfortunately almost all of the them were uploaded as scanned documents, with little or no ability to search, and heavily redacted in parts (often with no justification).
Here are the Justice briefing papers, including some odd removals of the names of all the senior staff in the Department, but with no reference as to why they were removed (that I can find). I would assume there were security considerations, but this is not mentioned in the redactions table. The document has been OCRd.
