Despite previous reports, it has now been revealed that Meghan Markle will not be joining her husband on the trip to Balmoral.
Earlier today, it was reported that the Duke and Duchess of Sussex were due to make the journey to Balmoral to be with the Queen following Buckingham Palace's announcement regarding the monarch's health.
Just after midday on Thursday, September 8, Buckingham Palace shared the following statement:
"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 news, it was reported by BBC News that several immediate members of the Royal Family were traveling to Balmoral in Scotland in order to be at the 96-year-old's side.
BBC News initially reported that a representative for Prince Harry and Meghan Markle stated that the couple - who were both in London for a charity event later this evening - would be traveling to Balmoral together.
However, more recent reports have stated that Markle is now expected to remain in London, according to sources.
Additionally, Markle will not attend the WellChild awards that were scheduled to take place this evening.
Several members of the Royal Family - including the Duke of Cambridge, the Duke of York and the Earl and Countess of Wessex - were seen disembarking an RAF aircraft earlier this afternoon after landing at Aberdeen Airport.
Prince Charles, his wife the Duchess of Cornwall, and Princess Anne - who was already reportedly in Scotland carrying out various engagements - are now at Balmoral.
The Duchess of Cambridge will reportedly be staying in Windsor with the couple's children, who have recently returned to school.
In response to today's news, the new UK prime minister tweeted that the country should be "deeply concerned" about the Queen's wellbeing.
"The whole country will be deeply concerned by the news from Buckingham Palace this lunchtime," Truss tweeted. "My thoughts - and the thoughts of people across our United Kingdom - are with Her Majesty The Queen and her family at this time."
The PM's message comes just two days after she was invited to start a government by the Queen during an engagement at Balmoral.
Additionally, Labour leader Sir Keir Starmer also shared his concerns about the news, tweeting: "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."
