New Year, New Promotion: Kate Middleton Set to Receive a 'Huge' New Royal Role

Kate, Princess of Wales, turns 42 on Tuesday, January 9, and this, combined with her role as a queen-in-waiting, may prompt King Charles III to bestow his daughter-in-law with new honors this year. One such position would be a "huge boost to the British industry" and would see "interest go through the roof, particularly in areas such as fashion and lifestyle," a source shared.

The Princess of Wales is rumored to be an appointee to the Most Noble Order of the Garter, which was established in 1348 by King Edward III and is the most senior Order of Knighthood in Britain. If selected, which is always the personal decision of the monarch and not the government, Catherine would be known as a Royal Lady of the Order of the Garter.

Her Royal Highness would join eight other women in the chivalry, including Queen Camilla, Princess Anne and Princess Alexandra. The King and Kate's husband, William, Princes of Wales, are also in the order.

Additionally, His Majesty may also appoint his daughter-in-law with the ability to grant royal warrants throughout the United Kingdom. Warrants are as old as the monarchy itself and are typically given by the reigning sovereign as well as any member of their family they also invest with the power. This is typically only the monarch's consort and heir, which would be the Queen and William, however, royal analysts predict Charles III may tap Kate as well.

Burberry and Barbour are two famous British brands that have the royal coat of arms on their business, and an upcoming review of some 800 companies with warrants will likely see more additions join the roster.

The Princess of Wales has won praise recently for how she handled her new role as Britain's Crown Princess in the last year.

"Her dedication to duty and work with charities has not only made her hugely popular with the public but respected too. And I think it’s this level of respect and class — similar to what the Queen had — that is getting the royal family through [these claims]," PR expert Denise Palmer-Davies told an outlet.

She concluded: "Kate is following the Queen’s key rule of 'never complain, never explain' and is carrying on with her daily duties. We have seen her out and about at important engagements, smiling and showing the world she is strong, and that’s the shield. It’s a shield of strength and stoicism, really."

The princess is expected to spend her birthday at Adelaide Cottage on the grounds of Windsor Castle with her prince and their three children, Prince George, Princess Charlotte and Prince Louis.

"They'll be at Windsor as the children are just about to start back at school, so it will just be family. But to be honest, that's just the way she likes it," a royal source spilled.
