Why Kate Middleton and Queen Camilla Won't Sport Tiaras During President Biden's U.K. Visit

King Charles welcomed U.S. President Joe Biden to Windsor Castle for their first formal meeting of the new royal reign

President Joe Biden met with King Charles at Windsor Castle, but the trip will be without the full glamour that sometimes comes with foreign visits to the United Kingdom.

Although King Charles, 74, and Biden, 80, have met before, Monday's meeting was significant as the first formal meeting during the new royal reign with the United States president. However, Biden's visit was a working visit rather than an official state visit, which can be accompanied by a palace banquet — complete with royal women like Queen Camilla and Kate Middleton, the Princess of Wales sporting tiaras.

Earlier in the day, Biden met British Prime Minister Rishi Sunak. From the U.K., the president will travel to Lithuania for the NATO Summit and Finland for a U.S.-Nordic Leaders Summit, the White House said.

A U.S. state visit may occur at a later date — in April, the White House said that Biden accepted King Charles' invitation for a state visit during a phone call ahead of the monarch's coronation.

President Barack Obama and First Lady Michelle Obama previously headed to the U.K. for a state visit in 2011, and President George W. Bush and First Lady Bush were the guests of honor in 2003. Queen Elizabeth, who died in September, made four state visits to the U.S., the last being in 2007 to celebrate the 400th anniversary of the Jamestown settlement, in addition to other visits.

Most recently, President Donald Trump arrived in the U.K. for a three-day state visit in June 2019 after being invited after he was sworn into office two years earlier.

Queen Elizabeth, Princes Anne, Camilla (then known as the Duchess of Cornwall) and Sophie (the Duchess of Edinburgh, then known as the Countess of Wessex) all wore tiaras for a state banquet at Buckingham Palace. Kate did not attend the banquet.

The first state banquet of King Charles' reign in the U.K. was held in November when the President of South Africa, Cyril Ramaphosa, visited the country. At the Buckingham Palace event, Kate made her tiara debut as the Princess of Wales in her go-to headpiece for such occasions: Queen Mary's Lover's Knot tiara.

Queen Camilla also sported her first tiara of King Charles' reign for the state banquet, a sapphire and diamond tiara that Queen Elizabeth wore for a 2015 state visit with President of China Xi Jinping.

But Princess Kate's most recent tiara moment (also in Queen Mary's Lover's Knot tiara) came last month at the royal wedding of Crown Prince Hussein and Princess Rajwa of Jordan — and First Lady Jill Biden also attended the glamorous event!

The Princess of Wales and the First Lady teamed up in 2021 to champion education. While Biden is a lifelong educator, Kate has made highlighting the importance of the first, formative years in life one of the key missions of her royal work.
