The directive stated that the Government had no need to respond because of the overwhelming public support, and should instead "lead the changing conversation".

"Instead we can dismiss."
The memo also included "key messages" for ministers and staff to stick to in their written statements, including: "No one had the luxury of time," and, "Perfect would have been the public enemy of the good".
It also suggested ministers say: "Tough calls had to be made... The results speak for themselves."
Another point noted: "Evidence shows our decisions were the right ones".
