It was announced today that the Queen was placed under medical supervision due to concerns over her health.
While no further announcement has been made, it will not surprise you to know that lengthy and detailed plans have been set out for the event of her passing.
If the 96-year-old passes at her Balmoral home in Scotland, 'Operation Unicorn' will come into effect.
It details that Scottish parliament will suspend operations to prepare for her state funeral.
Thousands are expected to flock to Scotland to pay their respects to the Queen, likely gathering around landmarks on Edinburgh's Royal Mile like Scottish Parliament, the Palace of Holyrood House and St Giles’ Cathedral.
The Queen would then be taken from Aberdeen to Edinburgh on a royal train, with servicemen and women lining every platform along the way.
Once the Queen arrives in Edinburgh, she would be temporarily taken to the Palace of Holyroodhouse, then carried to St Giles' cathedral.
This would give officials and members of the public the opportunity to say goodbye to the Queen before she is taken on another royal train from Waverley to London, again with armed officers lining the platforms the entire way.
Operation Unicorn ceases when the Queen leaves Scotland.
A statement was issued earlier today, which confirmed that there were concerns over her state of health.
In a statement Buckingham Palace said: "Following further evaluation this morning, the Queen’s doctors are concerned for Her Majesty’s health and have recommended she remain under medical supervision.
"The Queen remains comfortable and at Balmoral."
Following the release of this statement, it was reported that the Queen's family, including the Prince Charles, Prince William, and Prince Harry had travelled up to Scotland with their loved ones.
Following the announcement, Prime Minister Liz Truss said: "The whole country will be deeply concerned by the news from Buckingham Palace this lunchtime.
"My thoughts – and the thoughts of people across our United Kingdom – are with Her Majesty The Queen and her family at this time."
Labour leader Sir Keir Starmer said he was 'deeply worried' by the news and that he was hoping for the Queen’s recovery.
He wrote in a tweet: "Along with the rest of the country, I am deeply worried by the news from Buckingham Palace this afternoon.
"My thoughts are with Her Majesty the Queen and her family at this time, and I join everyone across the United Kingdom in hoping for her recovery."Featured Image Credit: Alamy
