Ashton had survived wide-ranging reviews of his performance after both the World Cup and the Six Nations and was given Andrew's backing each time.
This support only evaporated in the last month under pressure from the Management Board, when it became clear Johnson was ready to help the national cause.
The RFU's dreadful managing of the affair has left them looking like a mean-spirited and uncaring employer.
Former England hooker Brian Moore said: "If the first review of Ashton had been done properly there wouldn't have been any need for a second one. It is immensely frustrating and the whole process has been a PR disaster."
