Kate Middleton struck a sombre figure as she arrived at Windsor Castle for Prince Philip's funeral.

The Duchess of Cambridge was one of the thirty mourners saying their final goodbyes to the Duke of Edinburgh.

Her demure outfit consists of a black face mask, a black dress and a black fascinator, punctuated by simple pearl earrings and a quadruple-strand pearl necklace.

Kate was seen speaking with Prince Harry after the funeral - a deeply moving service which had the Queen sit alone due to Covid restrictions.

The Duke of Sussex appeared to be smiling beneath his face mask as he spoke with his sister-in-law.

Moments later William and Harry found themselves walking at each others side away from the Chapel.

Kate seemed to slip away from the pair, giving them space after many months apart to talk.

Although separated in age by six decades, Philip and Kate were said to have shared a special bond as well as a similar sense of humour and devotion to duty.

They often stood close to each other when the royals gathered on the Buckingham Palace balcony for Trooping of the Colour, and could be seen exchanging jokes on several occasions.

In one particularly touching photo the Duchess of Cambridge was seen laughing uproariously at a comment made by Philip.

When Prince William paid tribute to the Queen's husband following his death he made sure to note the bond his wife and grandfather shared.

"I will always be grateful that my wife had so many years to get to know my grandfather and for the kindness he showed her," he wrote.

Kate also had a sweet connection to her future grandfather-in-law years before meeting William, as she completed her Duke of Edinburgh Award.

Work-wise, Kate joined Philip and the Queen for a day of royal engagements in Leicester back in 2012.

The trio travelled to the city on the Royal Train, which means they spent the evening before together.
