This includes: "The manner of the presentation of government reports, particularly those from the Treasury, and the decision to spend £9.3m on sending a leaflet, advocating a Remain vote, to all UK households, were inappropriate and counterproductive for the Government. While the Government did not support a Leave vote, they nonetheless had a constitutional and public obligation to prepare for both outcomes from the referendum."
Amen to that. There was never any doubt that the government supported Remain and, sadly, the Civil Service were not seen to be impartial.
I would imagine many of the EU Directives and Regulations will be adopted by a post-Brexit Parliament, if it allows us ever to reach post-Brexit. It will also demonstrate just how many EU Regulations and Directives there were that Parliament had never approved previously.
