Boris Johnson: What happens now he's resigned?

One day you're the prime minister. The next day, you're not.

And that moment has arrived for Boris Johnson, who has made his last speech as PM and departed 10 Downing Street for the final time.

Liz Truss will be taking over and addressing the nation later outside the famous front door.

It can all change so quickly, but what happens when life suddenly stops as PM?

After his final speech, Boris Johnson is headed to Balmoral. To make his exit official, he still has to officially resign by meeting the Queen.

Normally, this would take place at Buckingham Palace, but Her Majesty has suffered from mobility issues and it is understood the change was made to prevent the need for any last-minute rearrangements.

If he's lucky, he will be given a personal gift by the Queen. Former PM Gordon Brown and his family got a signed photograph.

What might Boris Johnson do immediately after that? He could look to a few former prime ministers for inspiration.

We know sleeping is an option - Gordon Brown revealed on David Tennant's podcast that "you're very tired so you sleep for a bit".

Or he could choose to follow his passions - like former Prime Minister John Major did on the day he left office.

He said it was "time for lunch and some cricket" as he headed to the Oval to watch Surrey.

Boris Johnson - who's displayed a fondness for tennis - could jet off to America to watch the US Open.

Imagine losing your job AND your house on the same day.

"It's pretty dramatic," says Gordon Brown.

"In Britain, when you go, you not only lose the title, but you lose the house overnight and any ability to present yourself as something."

Boris Johnson will have spent just over three years living in Downing Street, welcoming the biggest politicians in the world, such as Donald Trump and Justin Trudeau.

He's also had access to Chequers - a luxury country estate where a prime minister usually goes to chill out.

These places will no longer be there for him to use, but house-hunting might not be an issue. He's thought to own several homes that he could be seeing more of soon.

We all see the police officers who follow the prime minister around and provide security. But what happens after you give up the top job?

Previous prime ministers continue to receive security, so it's likely it will be the same with Boris Johnson.

But that isn't always a good thing. Former Home Secretary Lord Douglas Hurd says your security "expects to know what you're going to be doing all of the time".

And let's not forget that, as prime minister, there is a big support system of secretaries, clerks and IT specialists who take care of everything when you are in the top job.

However, they will be staying in Downing Street with the new PM - whoever that turns out to be.

That means Boris Johnson might just have to go back to doing everyday tasks such as calling people and writing letters himself.

Although if he stays on as an MP he will still have assistants to support him.

You might remember that the prime minister has a nice official chauffeur-driven government car to take them around the country.

As all former prime ministers are also entitled to one, you'll probably continue to see Boris Johnson being driven around in a large Jaguar.

But what about travelling around the world?

There's a massive RAF plane that takes the prime minister abroad to conduct important business, such as talks on the Russia-Ukraine war.

Unfortunately, he won't be able to continue using it so will have to take commercial flights like the rest of us or charter a private jet.

• Who could be the next prime minister?
• Can Johnson stay on until the autumn?

Boris Johnson could continue serving as an MP, which is what Theresa May did, bringing him a salary of £84,144 per year.

He could also write a book, something predecessors Tony Blair and Gordon Brown have done.

Or, he might choose to leave politics all together and spend his time riding Boris bikes.
