The Princess of Wales was impeccably graceful as she arrived at Canterbury Cathedral for the installation of the new Archbishop on Wednesday, even dodging high-force winds by skillfully holding onto her hat.

Kate, 44, had joined her husband, Prince William, to support Dame Sarah Mullally for her enthronement ceremony at the UNESCO World Heritage Site in Kent – a significant occasion, as she could one day crown them King and Queen.

The couple were as affectionate as ever and were seen chatting in their seats in the quire before receiving the traditional bow from the new archbishop.

In one picture, the royal mother-of-three even appeared to be licking her lips while looking at her husband. Moments earlier, she had been gazing at William as they met faith leaders, before averting her gaze.

Speaking to HELLO!, body language expert Inbaal Honigman commented: “Catherine’s compressed lips could have two meanings. Firstly, it is a mark of tension. Her lips are stretched and thinned and her mouth is closed. These signify stress, anxious thoughts and worries.

“The other meaning of lips that are compressed so tightly is self-censorship. Catherine’s dimples are showing, which gives the impression that she’s not hiding a bad secret but a nice one. Her eyes, looking straight at someone or something, are focused and alert, which could suggest that this stress, or indeed her secrecy, is on behalf of someone else. She could be sending a subtle signal to William, reminding him to be discreet about something.”

The couple was representing King Charles, just days after William reaffirmed his “quiet” religious faith. William will one day be Supreme Governor of the Church of England and hold the title Defender of the Faith.

A historic occasion

The Waleses smiled and clapped along with the 2,000-strong congregation as those gathered for the historic service erupted with applause after Dame Sarah was formally enthroned.

William and Kate, who had no active role in the ceremony, listened to the first sermon by the new Archbishop, in which she spoke of her hopes for peace in the Middle East, and acknowledged failures on safeguarding in the church.

The Princess appeared to be licking her lips

While the King is head of the Church of England, the Archbishop of Canterbury is the most senior bishop and the spiritual leader of the Church and the worldwide Anglican Communion.

The ceremony featured a mandate – a legal instruction – from the King, which was read by the Principal Registrar of the Province of Canterbury, Darren Oliver, giving the monarch’s instruction to install Dame Sarah in the role.

As the prince and princess arrived at the cathedral on Wednesday afternoon, Kate, in a long grey fitted Suzannah coat, held on to her wide-brimmed Juliette Botterill hat amid windy weather in Canterbury.

The congregation, including Prime Minister Sir Keir Starmer, stood while the Waleses processed side-by-side through the nave to their seats in the quire, as a royal fanfare sounded.

William’s Christian beliefs

Prince William confirmed his “quiet” commitment to the church this week

Unlike King Charles and his grandmother, Queen Elizabeth II, he does not attend church every Sunday. Instead, he attends services for important occasions such as Christmas and Easter, or weddings.

Three days ahead of Dame Sarah’s installation, an aide to the 43-year-old prince sought to draw a line under debate on William’s stance on religion by saying he had a “quieter” commitment to the Church of England.

The aide added: “He understands the importance of the role he will inherit and is committed to carrying it forward with sincerity, authenticity and a clear sense of purpose.”
