King Charles 'could cause friction' as he 'plans to bestow Princess title on Zara Tindall'

King Charles is reportedly considering bestowing the title 'Princess' on his niece Zara Tindall.

After revealing he was diagnosed with cancer earlier this year, the King has had an evolving number of royals working for the family and supporting him.

One royal who has stepped up since then has been 43-year-old Zara Tindall, who is said to be very close to her uncle, with the pair recently being spotted together at the Windsor Horse Show.

Pictures from the event showed Zara greeting the King with a warm smile and a loving embrace.

Zara, the daughter of Princess Anne, was not given the title at birth after her mother declined, in the same way she did with son Peter previously.

It is thought Anne once said it was a "mixed blessing" being a princess, instead wanting her own children to go through life without their royal heritage weighing on them.

According to New Idea, Zara once said: "We were very lucky that we got to do it a bit our own way."

The publication, however, also says Anne, a 'steadfast supporter' of her older brother could raise questions about any potential titles given to her daughter.

It claims: "There's talk that niece Zara Tindall, 43, who is very close to her uncle (as witnessed by their loving moment at the Windsor Horse show recently) might become more involved in this side of things, and that Charles is keen to support such an interest by bestowing on her the title of princess."

The publication goes on to suggest Charles believes Zara should have been given the title 'all along'.

It adds: "So while Anne has always been a steadfast supporter of her older brother, this is likely to cause some friction between the two.

"In trying to make life a little easier, could such a move in fact prove problematic for Charles?"
