Princess Kate’s return to royal life has so far been shrouded in mystery, but a royal expert has suggested that there are two potential dates on which she could make her return.

The Princess of Wales has been out of the public spotlight since March following the announcement of her cancer diagnosis.

She addressed the nation in a personal video message announcing her diagnosis after undergoing major abdominal surgery in January and beginning chemotherapy in late February.

To date this year, Kate has only made two major public appearances – at Trooping the Colour in June and at the Wimbledon men’s final in July.

Ahead of her appearance in June, the princess said in another personal message: “As anyone going through chemotherapy will know, there are good days and bad days.”

Friends of the princess say her good and bad days “still rings true”, according to an analysis by The Times’ royal editor Roya Nikkah.

She continued to add that more “good days” could lead Kate to set her sights on a “potential” return to public life for the National Service of Remembrance on November 10.

If the date does go ahead, it would mean she would join the King and Royal Family at the Cenotaph.

However, according to Nikkah, royal aides are also understood to be making separate preparations.

Nikkah understands that Kate could alternatively make an appearance at the “Together at Christmas” carol service in Westminster Abbey.

As the annual event is televised, it could be the case that she leaves a video message if she doesn’t end up going in person.

According to Nikkah, Kate has been holding regular meetings with her private secretary, assistant private secretary and the Waleses’ communications secretary to plan for the future.

Speaking to GB News back in August, historian Simon Heffer claimed Princess Kate’s return to royal life gives people hope for a “bright future”.

Speaking to GB News, Heffer said: “She’s enormously popular. And the fact that she turned up at Wimbledon and Trooping the Colour, I think he’s reassured people that she’s not perhaps as ill as some of them feared.

“It’s quite clear that she’s being very ill and that her recovery is going to take some time.

“I think that it’s made people feel more confident that [the monarchy’s] got a bright future.

“And everybody wishes her a rapid and complete recovery. And it’s been good for morale to see that she can do these things now.”
