King Charles speaks to a royal fan about her King Charles spaniel named Camilla at Easter service

King Charles shared a comical exchange with a royal fan about her 17-year-old spaniel named ‘Camilla’ as he greeted the public on Easter Day.

Charles and Camilla shook hands with dozens of people queuing outside St George’s Chapel in Windsor yesterday in what was the most important public appearance for the monarch since his cancer diagnosis last month.

A woman, holding a Welsh flag and wearing a matching bright red coat and hat, called King to get his attention.

She said: ‘Your Majesty, Camilla is now 17’. Charles looked back at her and paused for a moment before clarifying that her King Charles spaniel’s name is Camilla.

The king made a comment to the woman and the crowd began to laugh at the altercation.

Moments earlier, the King and Queen were asked to pass on the ‘best wishes’ from a member of the public to the Princess of Wales.

The woman said, “Best wishes to the Princess of Wales,” to which Camilla nods in agreement. King Charles replied: ‘Thank you very much.’

The King was seen shaking hands with 56 people as he was presented with a handmade card and promised concerned royal fans he would do his ‘best’.

The Prince and Princess of Wales were not present as they continue to privately recuperate with their three young children at Amner Hall, their country home – where they can ‘shut off from the world and move on’.

Following Kate’s emotional video last Friday, the king said he was “so proud” of the princess for her courage to speak out, and that he had “the closest contact with his beloved daughter-in-law.”

The outpouring of support comes after the royal family was shocked by not only King Charles’ illness, but also the Princess of Wales’ cancer diagnosis.

Just over a week ago, Kate, 42, revealed she was undergoing preventive chemotherapy in an emotional video that sent shockwaves around the world.

The 75-year-old monarch was in good spirits and his visit could be seen as a very “important” step in his recovery from cancer, a Palace source said.

Charles was diagnosed with shock cancer just 17 months into his reign as king, while undergoing a hospital procedure for a benign prostate enlargement.

Speaking to MailOnline, the Palace source said today’s walkabout marks an ‘important’ step in Charles’ recovery, adding: ‘As can be seen, the King has responded very encouragingly to the treatment in recent weeks.

“His doctors were thus able to adapt their guidance somewhat to what His Majesty can now undertake, including attending the Easter service and greeting well-wishers who had kindly come to show their support.

‘To be clear, His Majesty’s treatment continues and caution is of course the key word, but as agenda plans evolve towards the summer we hope to see more of these carefully calibrated steps towards the resumption of some public duties for The King, with adjustments made where necessary.

‘Nothing will be confirmed until closer, plans remain in flux and are subject to medical guidance, but there is great hope and optimism among both doctors and patients.’

The source added that while His Majesty has carried out all his official duties privately and has been photographed at a number of smaller palace gatherings, today is likely to have provided reassurance to a wider public that His Majesty is “doing well and the way forward looks bright.” very positive’.

During today’s walkabout, a royal fan leaned over to say to Charles: “Happy Easter, Your Majesty, stay strong and never give up.” Others were heard saying ‘nice to see you’ and asking the monarch ‘how are you’ as Charles and Queen Camilla walked past.

Earlier today, the King was seen beaming as he arrived in his maroon Bentley ahead of today’s church service. It marked a “soft” return to public life after he stepped down from normal duties last month.

The King’s cheerful demeanor will provide great reassurance to the public after the monarch stepped back from official duties following his diagnosis last month.
