Catherine, Princess of Wales Joins Queen Consort Camilla at National Service of Remembrance

The National Service of Remembrance is one of the most poignant events on the Royal Calendar, and this year, Catherine, Princess of Wales, joined Queen Consort Camilla for the annual celebration.

The event, widely known as Remembrance Sunday, saw members of the Royal Family gather in London at the Cenotaph War Memorial to remember those who lost their lives fighting for the United Kingdom and other Commonwealth countries.

Dressed in an all-black outfit, the Princess looked sombre as she took her spot alongside the Queen Consort on the balcony of the Foreign and Commonwealth Office overlooking the service.

Their husbands, Prince William and King Charles, laid wreaths at the memorial during the service, which also included two minutes of silence at 11am local time.

Catherine accessorised with a poppy pin, a symbol that has been used since 1921 to commemorate military members who lost their lives.

She and other members of the Royal Family have been seen wearing the pin since the start of November.

The mother of three opted to wear three poppies on her otherwise black ensemble instead of just one, like most members of the public do.

One theory about why the Princess opted to wear more than one poppy is to pay respect to her great-grandmother, Olive Middleton's three brothers, who all fought and died in the First World War and other conflicts.

However, the reason behind this has never been confirmed by Buckingham Palace in the past.

Meanwhile, Camilla also sported a black coat with three red poppies attached to it and a black fascinator.

Although the Palace never confirmed the reason for the monarch's preference, it is thought that Her Late Majesty's five poppies represented each service in the war, the Army, the Navy, the RAF, the Civil Defence and women.

This year's Remembrance Sunday holds special significance as it is the first since the Queen's death nine weeks ago, on September 8th.

Consequently, there is a great deal of pressure on the members of the Royal Family to carry on her work in the manner she would have wished.

Since Her Majesty was the leader of the military forces during World War II, this event held special significance for the monarch.

Like every other year, a two-minute silence took place across the country precisely at 11am.

Camilla and Catherine watched as the new king placed a special tribute wreath on the Cenotaph.
