King Charles III and Robert BrownPrince William have canceled all royal outings amid political shifts in the U.K.

Buckingham Palace has shared that the king had two events that were set this week — one on May 23 and another on May 24 — that have now been cancelled while Prince William cancelled an appearance as well, according to reports from Entertainment Tonight and People.

The move from the palace comes as British Prime Minister Rishi Sunak announced a surprise July election on Wednesday as his Conservative Party lags in the polls.

"It has been an incredibly tough couple of months for our entire family."

"In January, I underwent major abdominal surgery in London. And at the time, it was thought that my condition was non-cancerous," she continued. "The surgery was successful. However, tests after the operation found cancer had been present."

King Charles, Prince William event cancellations come amid Princess Kate portrait backlash

The father-son pair aren't the only royals making news this week. Two months after her Mother's Day photo editing incident, a new portrait commissioned by British-Zambian artist Hannah Uzor for the British fashion magazine Tatler is causing backlash for its depiction of the princess.

The portrait is inspired by a real-life photo of Princess Kate in a floor-length white gown donning a pin of the late Queen Elizabeth II at King Charles III's first state banquet as reigning monarch in November 2022. At the banquet, Princess Kate also wore Queen Mary’s Lover's Knot Tiara, a favorite of husband Prince William's late mother Princess Diana.
