It has been over two months since Princess Catherine has been officially seen out in public.

Now, a photograph posted on Mother's Day appears to show the Princess looking happy and healthy.

However the image has been branded as having been "manipulated" by international news agencies who have pointed out flaws in its appearance before pulling it from their sites - fuelling circulating theories about the Princess's health.

The Princess underwent "planned abdominal surgery" on January 16, with Kensington Palace announcing the Princess had returned to her home in Windsor on January 29.

She was said to have made "good progress" in her recovery since leaving The London Clinic, where King Charles III was also undergoing treatment.

Details of the Princess’s condition have not been revealed but Kensington Palace previously said it was not cancer-related and that Catherine wished her personal medical information to remain private.

The Princess has managed to avoid the public eye since her Christmas Day appearance leaving a church service at Sandringham.

This was until American paparazzi allegedly took a photo of what they claim was Catherine and her mother in a black Audi driving in Windsor.

It has previously been said that Catherine will return to official duties after Easter.

Catherine’s parents, Carole and Michael Middleton, and siblings, Pippa Matthews and James Middleton, were said to be hands-on in helping the Walese's.

A week after the paparazzi shot, The Prince and Princess of Wales released a family photo to mark Mother's Day.

Surrounded by her three children Prince George, Princess Charlotte and Prince Louis, the Princess is sat on a chair - with the Palace confirming Prince William was behind the camera.

Alongside the image, the Royals wrote: "Thank you for your kind wishes and continued support over the last two months. Wishing everyone a Happy Mother's Day. C."

On closer inspection, news outlets and social media sleuths began to spot imperfections in the picture, including a noticeable edit around the cuff of Princess Charlotte's sleeve.

Just hours after the photo was published on the Royal's social media accounts, news agencies began to issue Photo Kill Notices - retracting the image from circulating alongside their news stories as it was deemed to have been "manipulated".

With conspiracies already rife over the Princess's condition and whereabouts, the image further fuelled the fire of doubt against the Royal family.

A day later on Monday, an apologetic statement was published on the Royal's social media.

It read: "Like many amateur photographers, I do occasionally experiment with editing. I wanted to express my apologies for any confusion the family photograph we shared yesterday caused. I hope everyone celebrating had a very happy Mother’s Day. C"

That same day the Princess was photographed leaving Windsor in a car with Prince William - with Kensington Palace confirming the pictures were legitimate.

Despite this, six news agencies, including PA Media continue to state there is a kill notice on the Mother's Day image and are seeking "urgent clarification" about the manipulation.

Kensington Palace continue to face questions and scrutiny about the photograph.
