What happens to a Prime Minister after they resign? That's the question many of us will be asking about Boris Johnson, who made the nation get up ridiculously early for his bonkers final speech before he finally left. He might follow in the footsteps of David Cameron, who stood outside 10 Downing Street alongside his family to give his resignation speech back in June 2016.
Despite claiming he would continue as a Conservative backbencher, he made a quick U-turn by September and announced he was giving up his seat and "sped away without glancing back". Mr Cameron resigned as Prime Minister just a few hours after the result of the EU referendum was announced - with the UK voting to leave.

Speaking outside No. 10, he said "fresh leadership" was needed and that he would attempt to "steady the ship" in his final few months.
"The British people have voted to leave the European Union and their will must be respected," said Mr Cameron. "The will of the British people is an instruction that must be delivered."
He added: "I do not think it would be right for me to try to be the captain that steers our country to its next destination."
At his final Prime Minister's Questions, Mr Cameron joked "I was the future once", a reference to his 2005 quip at Tony Blair, before submitting his resignation to the Queen later that day.
The former PM had vowed to carry on working for his constituants, but in September 2016 he stood down as an MP and triggered a by-election in his Oxfordshire seat of Whitney.
Mr Cameron claimed he did not want to be a "big distraction and diversion" for his successor, Theresa May, but denied his announcement was related to the government's moves towards allowing new grammar schools.

"Obviously I'm going to have my own views about different issues," he said. "People would know that and that's really the point. As a former prime minister it is very difficult, I think, to sit as a backbencher and not be an enormous diversion and distraction from what the government is doing."
In October 2016, Mr Cameron became chairman of the National Citizen Service Patrons and in January 2017 he was appointed president of Alzheimer's Research UK.
Few of his post-premiership ventures have done very well, with one company he was working for collapsing and another being embroiled in scandal.
Mr Cameron went to work for Greensill Capital as an adviser - with Australian banker Lex Greensill having previously being brought in as an unpaid adviser when he was Prime Minister.
He came under fire when it emerged that he had sent texts to Chancellor Rishi Sunak's private phone to call for financial support through the Government's Covid Corporate Financing Facility.
The company subsequently went bust after its application for support was rejected - and Mr Cameron was cleared of breaking lobbying rules over his pleas to Mr Sunak to help Greensill Capital as it teetered on the brink of collapse.
The former PM was chairman of software firm Afiniti's advisory board from 2019 until November last year, when he quit after its founder, Zia Chishti, was accused of sexual harrassment.
A statement from Mr Cameron said the alleged events took place before he started his job and he did not know about the incident until it was made public.
Mr Cameron's office released a statement saying he had resigned as chairman of the company's advisory board "with immediate effect", "with regret, given the success and promise of this exciting company, and the commitment, dedication and loyalty of the many hard-working employees with whom he has enjoyed working."
On September 2019, the former PM published a memoir, For The Record, in a reported £800,000 contract - but the sales figures were not very impressive.
In the memoir he revealed how wife Samantha helped convince him to come out in support of gay marriage, why he moved Michael Gove out of education and swearing in front of the Queen.
As for Samantha herself, she unveiled a new clothing line in Vogue magazine, Cefinn, in 2017 which was named after the initials of the their children.
But the label came under fire last November after seeking unpaid interns in a move that risked breaching minimum wage rules and made a substantial loss.
"There are some people who don’t shop with us because of who my husband is," the former first lady told the Women Mean Business Live conference.
In 2018, she told The Times that she "really didn't enjoy" her time in No. 10 beyond the opportunity to meet "some amazing people".
There was a scandal in February 2020 when Mr Cameron's bodyguard was suspended after leaving a loaded gun in a toilet on a flight from New York to London.
A "terrified passenger" provoked panic after finding the 9mm Glock 17 pistol - along with passports belonging to Cameron and the Metropolitan Police close-protection officer - in the loo of the BA plane.
The force told the Mirror: "We are aware of the incident on a flight into the UK on 3 February and the officer involved has since been removed from operational duties. We are taking this matter extremely seriously and an internal investigation is taking place."
With things not going amazingly well for Mr Cameron, there were reports in November 2018 that he wanted a return to frontline politics because he was "bored s***less".
The former Prime Minister reportedly told friends he was mulling a return to politics and was hoping to be made Foreign Secretary.
A source close to Cameron has told The Sun: "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."
But nothing ever came of the speculation - with Mr Cameron actually turning down an offer from Boris Johnson to lead the COP26 climate change conference in Glasgow last November.
His former climate change minister Greg Barker, who was speaking on Newsnight, said: "My understanding is that he felt it was just a little too soon for him personally to come back into a front-line political role."
He may have stepped away from politics, but the former PM still has a lot of power and influence.
In July, The Mirror exclusively revealed that Mr Cameron, whose mum Mary has Alzheimer's, had persuaded the Tories to double funding into dementia research with a £150million-a-year boost.
Addressing scientists, he said: "Last week I met the Health Secretary and can reveal exclusively that he said they were going to have a 10-year dementia strategy and double money going into research.
"We’re a country of 60 million people and soon we’re going to have one million people tipping into this world of darkness. And quite apart from the emotional pain, and I see that with my mother, who is in her late 80s, think of the cost.
"This is now costing more than stroke, more than heart disease, more than cancer. We’re only going to crack this through scientists."
