One day you're Britain's prime minister, the next, you're not.
So what do you do after you've held the country's top job? Which perks do you keep and which do you lose?
Our World News Editor Kate Gregan reports.
Imagine losing your job AND your home on the same day.
Politics is a tricky business -- and for ex-prime ministers in the UK, it can be tough to navigate a new life once the gig is up.
One of the biggest perks to walk away from is perhaps the home itself.
A spacious four-bedroom flat above number 11 Downing Street.
It's perfectly located in central London, features 24-hour security and the use of a large garden.
Ex-Prime Minister's also forgo the use of Chequers -- a luxurious country estate outside the capital.
But some silver linings that come with the pressure of being Prime Minister do last a lifetime.
All former PMs get to keep their protection teams -- which also means the use of an armoured car.
They're also entitled to claim up to 115,000 pounds (NZ$223,658) a year to cover staff and office costs.
But what have some former leaders gone on to do?
After a tearful exit from Downing Street, Margaret Thatcher swapped the green benches for the red ones, taking her seat as Baroness Thatcher in the House of Lords.
After John Major lost the 1997 election, his first instinct was to watch some sport.
He took on a series of corporate roles, and was appointed a special guardian to Princes William and Harry.
In 2007, Tony Blair left number 10 and Parliament.
He's now SIR Tony Blair -- advising companies and governments -- and has found time to write an autobiography.
In 2016, David Cameron resigned after the UK voted to leave the EU.
He became president of Alzheimer's Research UK, and took on various corporate roles.
Theresa May had a painful departure in 2019.
But she decided to remain in Parliament after stepping down as prime minister.
Like those that came before her -- her time at the top was destined to end.
