Kate Middleton spotted sending subtle message in first major return to royal life

Kate Middleton is finally back to her Royal duties, and fans have already spotted a subtle message during the event.

The Princess of Wales has been through a lot over the last year, as she underwent her cancer battle and chemotherapy treatments.

Since then, she had been taking care of her health in private, and limiting public appearances.

As many people began to grow more and more worried about her, she released a heartfelt message about her health and her plans for the future before sharing a beautiful video of herself and her family as she reflected on this time in her life.

Speaking about her cancer journey over images showing the Wales' and their children, Kate said in the clip: "Doing what I can to stay cancer-free is now my focus. Although I have finished chemotherapy, my path to healing and full recovery is long and I must continue to take each day as it comes."

She continued: "I am, however, looking forward to being back at work and undertaking a few more public engagements in the coming months when I can.

"Despite all that has gone before, I enter this new phase of recovery with a renewed sense of hope and appreciation of life."

Having vowed to get back to her duties, she has since come back to join her husband on Tuesday (3 December) to welcome the Emir of Qatar and his wife, Sheikha Jawaher.

This is now her largest appearance since finishing cancer treatment in September of this year.

As part of their State Visit to the UK, the Qatar couple were met by our royals to share their welcomes as the face of our nation.

However, people noticed that Kate sent two subtle messages for the occasion.

Not only did she tribute Qatar, she also paid homage to its flag through her fashion choice.

On the big day, Kate was seen wearing a maroon coat dress by Sarah Burton for Alexander McQueen and a matching Sahar Millinery hat.

The colours match Qatar's flag, along with a string of pearls that may have been paying tribute to Prince William's grandmother, the late Queen Elizabeth II, who used to own them.

Kate, the Princess of Wales, will not attend the evening's State Banquet at Buckingham Palace.

While Queen consort Camilla wasn’t there at the welcoming ceremony due to a chest infection, the Wales’ took charge.

The 77-year-old contracted her bug after travelling to Australia and Samoa over a month ago, and has been advised to rest.

The illness led to Camilla having to skip the Remembrance Sunday weekend as well as the Royal Variety Performance in November.

It was reported that the Queen now has post-viral fatigue and has decided to miss some of the outdoor activities.

For those of you who don’t know, post-viral fatigue is when a person suffers from extreme bouts of tiredness after a period of illness, and other symptoms can include memory problems and muscle pain.

While Camilla skipped the outdoor ceremonial welcome today, she welcomed the Emir of Qatar and his wife from inside the palace.
