A source whom the former Prime Minister confided in disclosed Mr Cameron would not rule out a return to UK politics if a future Tory leader asked him to come back.
The role Mr Cameron would assume is not entirely clear but the insider implied it could be Foreign Secretary.
Speaking to The Sun, the source said: “David is dedicated to public service, and has often said he wouldn’t rule out a public role one day, domestically or internationally.
“But he is only 52, and still a young man.”
The former Prime Minister, who initiated the Brexit referendum process which consequently produced the UK’s decision to leave the EU, is planning to release his political memoirs next spring.
Any bid to return to Westminster would have to wait until after the book’s release.
Mr Cameron has said he wants to hold back on the publication of the potentially explosive biography until after “Brexit day” on March 29, 2019.
His reasoning for delaying the memoir’s release date is so revelations from them do not undermine or interfere with the Brexit negotiations.
The old Etonian is expected to use the bombshell book to savagely settle scores with a number of acting senior ministers – in particular, Environment Secretary Michael Gove who shamelessly stabbed Mr Cameron in the front when he spearheaded the Leave campaign.
Mr Cameron and Mr Gove had been close friends, often holidaying together with their families before the sensational fallout.
The potential return has been met with backlash, with Labour’s Yvette Cooper among those critical of the plan.
On Twitter, she said: “What, because it worked out so well last time?
“Man, you ripped up our closest international partnership. By accident.
“That makes you even worse than Boris Johnson.”
Shadow education minister Angela Rayner branded the rumoured return of David Cameron to frontline politics as “bizarre”.
Ms Rayner tweeted: “Just when you thought politics couldn’t get any more bizarre.
“No, David, please stay in retirement you caused enough damage last time.”
Shadow communities and local government secretary Andrew Gwynne wrote: “God. No.
“Didn’t he do enough damage first time around?? Please spare us all.”
Meanwhile, Redcar MP Anna Turley said: “The sense of entitlement is unreal. Please go away and think about what you’ve done”, while Emily Thornberry posted a facepalm emoji – a picture used to display frustration or embarrassment at a certain situation.
Mr Cameron quit his premiership after a crushing defeat in the EU Referendum.
In part of his leaving speech, he said: “The negotiation with the EU will need to begin under a new Prime Minister and I think it is right this new Prime Minister takes the decision about when to trigger Article 50 and start the formal and legal process of leaving the EU.
“The British people have made a choice that not only needs to be respected but those on the losing side of the argument, myself included, should help to make it work.
“Britain is a special country, we have so many great advantages – a Parliamentary democracy where we resolve great issues about our future through peaceful debate.
“A great trading nation with our science and arts, our engineering and creativity, respected the world over.’And while we are not perfect, I do believe we can be a model of a multiracial, multi-faith democracy where people can come and make a contribution and rise to the very highest their talent allows.”
