Queen Elizabeth 'Has Been Amazing' Following Prince Philip's Death, Daughter-in-Law Sophie Says
Prince Edward and wife Sophie, Countess of Wessex visited the Queen on Saturday at Windsor Castle
On Saturday, Sophie and her husband Prince Edward, the Queen's youngest child with the Duke of Edinburgh, paid a visit to Windsor Castle.
As they left, Sophie, 56, tearfully told Sky News correspondent Rhiannon Mills that "the Queen has been amazing."
Prince Charles also paid his respects by visiting his mother on Friday, just hours after the Duke of Edinburgh "passed away peacefully" at Windsor Castle. Prince Andrew was also seen visiting on Saturday.
On Saturday morning, the official social media account for the monarch and her family members also shared a touching quote the Queen once said about her husband.
"He has, quite simply, been my strength and stay all these years, and I, and his whole family, and this and many other countries, owe him a debt greater than he would ever claim, or we shall ever know," she said about Philip in 1997.
Charles Anson, former press secretary to the Queen, told PEOPLE on Friday that the 94-year-old monarch was prepared for Philip's death after years of health troubles.
"She would have thought about this moment several times, and her way would be to remain as steady and as calm as possible," Anson said. "That comes naturally to her through her temperament and her experience."
"In my years of working for her she was always calm, no matter what was going on," he added. "But for any human being, this is a very cathartic moment."

Anson said the Queen will be surrounded by the close members of her private household in the coming days.
"She has an enormous amount of family support for her and will also take comfort from the enormity of the support from all over the world," he said.
