Royal sources admitted that he always intended to return to Whitehall.
It comes as Prince William and Princess Kate placed an online advert in September looking for an “emotionally intelligent” chief executive officer with a “low ego” to run their household.
The ad stated the new CEO will report directly to the royal couple – instead of the private secretary.
It added a successful candidate must be “able to operate as a ‘servant’ leader, empowering the senior team”.
However after the ad was published, employment experts warned the royal couple that a claim for discrimination can be brought by job applicants as well as by employees.
The Prince and Princess of Wales’s move is seen as quite the change in the royal household as up until now a senior royal’s team was headed up by a Private Secretary.
A source told the Times: “Having a CEO placed above you isn’t an optimal job scenario if you are JC and your title is no longer head of the household.”
