News of the queen's solo seating arrangement was first revealed on Friday, promopting Morgan, 56, taking to Twitter to react.
"The Queen, who has devoted her life to selfless public service, will be forced to sit all alone during the funeral of her husband of 73 years, due to covid restrictions. How heartbreakingly sad," Morgan wrote on Friday afternoon.
Then, on Saturday morning, just hours ahead of the ceremonial royal funeral, Morgan followed up with another tweet in which he shared that his thoughts would be with the queen throughout the day.
"Thinking of The Queen today as she says goodbye to the love of her life," Morgan tweeted along with two photos of Philip and Her Majesty gazing into one another's eyes.
Morgan notoriously left "Good Morning Britain" over his critical remarks about Meghan Markle following the Oprah Winfrey interview in March. Morgan's controversial comments were then supported by Sharon Osbourne on "The Talk," causing an intense on-air spat between Ozzy Osbourne's wife and co-host Sheryl Underwood. It ended with Osbourne leaving the show for good.
The ceremonial royal funeral was more low-key than past royal send-offs. The ceremony, code-named Operation Forth Bridge, was limited to 30 attendees, but it was one the Duke of Edinburgh had much participation in planning prior to his passing.
The Queen was joined by the four children she shared with Prince Philip – Prince Charles, Princess Anne, Prince Andrew and Prince Edward – as well as Charles's wife Camilla, Duchess of Cornwall, Anne's husband Timothy Laurence and Edward's wife Sophie, Countess of Wessex.
Additionally, each of Philip’s eight grandchildren -- who include Peter Phillips, Zara Tindall, Prince William, Prince Harry, Princess Beatrice, Princess Eugenie, Lady Louise and James, Viscount Severn -- attended the funeral.
Prince William's wife, Kate Middleton; Zara Tindall's husband, Mike Tindall; Princess Eugenie's husband, Jack Brooksbank, and Princess Beatrice's husband, Edoardo Mapelli Mozzi, also joined their royal spouses at the family event.
Members of the Royal Navy, the Royal Marines, the Royal Air Force and the British Army took part in the funeral procession. Philip’s coffin was carried to St. George’s Chapel on a specially adapted Land Rover, which he designed himself.
It was previously revealed that Prince Harry's wife, Meghan Markle, 39, would not be in attendance. The Duchess of Sussex, who is pregnant with the couple's second child, was advised by her doctor not to attend. The Duke and Duchess of Sussex settled down in Santa Barbara, California, last year, months after the couple announced their decision to step back as senior members of the royal family.
