The Queen's death has left the nation in mourning, as Her Majesty passed away aged 96, Buckingham Palace confirmed yesterday.
The palace issued a statement which read: "The Queen died peacefully at Balmoral this afternoon. The King and The Queen Consort will remain at Balmoral this evening and will return to London tomorrow."
There had been concerns for her health earlier that day, as the palace had issued a rare statement in which they said she had been placed under medical supervision, as doctors had voiced concerns for her health.
Prince Charles - now King Charles III - Camilla and Prince William all rushed to Balmoral to be by her side, while other members of the royal family were informed.
There will be plenty happening over the next 10 days as the nation mourns Her Majesty, but some Brits have also been left wondering of changes that come to the likes of money, postboxes and stamps all of which bear her name and portrait.
Amid those changes, a number of people have taken to social media asking if British passports will still be valid now that the Queen has passed away.
If you check your UK passport, it states: "Her Britannic Majesty's Secretary of State requests and requires in the name of Her Majesty all those whom it may concern to allow the bearer to pass freely without let or hindrance and to afford the bearer such assistance and protection as may be necessary.”
As it states that you can travel under the name of Her Majesty, some users have been confused as to whether passports will be valid.
One Twitter user wrote: "Now that the Queen is gone, does this mean we need to update our passport? It says we're under the protection of "her" Majesty on the front page. Asking for a friend."
Another asked: "With the death of the Queen, are passports still valid or will they have to get changed?"
British passports are still valid following the death of Her Majesty.
As King Charles III takes to the throne, it's likely that new passports issued will be tweaked to reflect the male pronouns of the new King.
For those who have passports still within date, it's likely that these will only need to be updated once they have expired.
When travelling overseas, The Queen did not require a British passport, as it was issued in her name - this will likely be the same for King Charles III.
All other members of the Royal Family will require passports.
