Kate Middleton could make a new announcement on her health amid growing pressures on Kensington Palace, an expert has said.

Kate has not taken part in any public duties since Christmas Day 2023 and has been missing from the spotlight since January, when she was taken into a clinic in London for abdominal surgery.

It is expected that she will not return to official duties until after the children return to school following the Easter holidays on April 17.

However, royal historian Hugo Vickers has said that there will be “more pressure” the longer Kensington Palace leave any announcement.

Mr Vickers told The Sun: "Well, it's not impossible, because there's been a lot of pressure on Kensington Palace, and the longer they leave it, I guess the more pressure there will be. So, I don't know, but let's wait and see. There could well be some kind of an announcement."

"It was suggested in the Sunday Times yesterday that there will come a point where Catherine, when she's fully better, you know, will in some way discuss maybe her illness whatever that may be in an appropriate way.

"That's all very much up in the air obviously."

Kate Middleton filmed at farm shop

It comes as The Princess of Wales was filmed smiling alongside her husband during a visit to a farm shop in Windsor.

Kate’s recovery from surgery appears to have progressed after footage obtained by The Sun showed her and William at the local business on Saturday.

In the video the princess can be seen with her hair down, wearing a black jacket and leggings, chatting with William and carrying a large white bag.

The Windsor Farm Shop is a short drive from their Adelaide Cottage home in the grounds of Windsor Castle.

Nelson Silva, who saw the royal couple, told TMZ: “I noticed a couple choosing loaves of bread and the woman turned her face and I felt like I had seen the face before. It was familiar.

“I went to my car and as they came out of the shop I just filmed them. I think they walked out through a gate out of the grounds. They just vanished and I didn’t see a car.

“Kate looked happy and relaxed. They look happy just to be able to go to a shop and mingle.

“Kate looked relieved, like it was a success going to a shop. It felt natural.”

The royal couple also spent Sunday morning watching Prince George, Princess Charlotte and Prince Louis taking part in a sporting event, according to The Sun.
