Reason why Kate Middleton wore three poppies during Remembrance Sunday royal appearance

Royal fans were happy to see Kate Middleton as she wore a heartwarming statement during the Remembrance Sunday ceremony.

The Princess of Wales stepped out alongside the rest of the royal family to attend the Cenotaph.

This marks her second appearance in a row at two major royal events, and people are over the moon to see the future Queen back on her feet.

She stood in silence next to the Duchess of Edinburgh with the rest of the UK at 11am, paying respect to those who died in the wars.

But royal fans noticed one detail that wasn't familiar to them.

The Princess of Wales wore a cluster of three poppies rather than one, and the reason behind it is very heartwarming.

The gesture is in loving memory of her great-grandmother's three brothers, who lost their lives in the First World War.

The streets of London were filled with thousands of people attending to pay their respects, as well as veterans who served in the Armed Forces.

It is the job of the King to lead the senior members of the royal family and political leaders through the ceremony, by taking turns to lay wreaths at the base of the Cenotaph.

The presence of both Charles and Kate was welcomed by the public, after both falling ill with cancer.

When the princess announced her cancer diagnosis in March this year, King Charles spoke very fondly of his daughter-in-law.

In a statement from Buckingham Palace, he said: "His Majesty is so proud of Catherine for her courage in speaking as she did.

"Following their time in hospital together, [his majesty] has remained in the closest contact with his beloved daughter-in-law throughout the past weeks."

The statement added that both Charles and Queen Camilla would 'continue to offer their love and support to the whole family through this difficult time'.

The Princess has undergone the necessary treatments, and is considered to be cancer-free.

Despite this, she recently opened up about the 'indelibly tough' year she had faced, noting that she is doing everything she can 'to stay cancer-free'.
