Peter Phillips and Harriet Sperling share romantic first kiss after fairytale wedding - best photos

Accompanied by her daughter, Georgina, and her two new stepdaughters, Savannah and Isla, as her bridesmaids, Harriet looked ethereal as she arrived at the church. 

An insider told HELLO! that Harriet was taking deep breaths in the car before getting out, calming her pre-wedding jitters in a very relatable moment.

Harriet looked beautiful in a lace and silk column-style gown with a dramatic train. She wore her hair up in a low chignon under a diamond tiara. 

Savannah, Isla and Georgina's bridesmaid dresses were also by Emilia Wickstead, paired with earrings from Aspinal London.

The bride and groom sheltered under a white parasol as they emerged from the church after tying the knot. 

The rain did not dampen anyone's spirits as the bridal party, made up of Peter's daughters, Savannah and Isla, and Harriet's daughter, Georgina, assisted with the bride's train and veil. 

A closer look at the bride's Pragnell tiara, which features glittering laurel leaves and floral motifs.

It's very similar to a tiara owned by Princess Anne in an official photograph to mark her 50th birthday in 2000.

The tiara has been worn by generations of Pragnell family members and was present at the coronations of King George VI and Queen Elizabeth II.

After the ceremony, the newlyweds departed for their wedding reception by car and shared a sweet kiss. 

The Prince and Princess of Wales were all smiles as they arrived, with Kate choosing a cream dress by Roland Mouret and a Jane Taylor boater hat for the occasion. 

The couple were not accompanied by their three children, Prince George, Princess Charlotte and Prince Louis. 

The King, dressed smartly in a morning suit with a butter yellow waistcoat, waved cheerfully to the crowds outside the church.

Queen Camilla looked elegant in a cream scalloped coat and matching dress as she waved to wellwishers. 

Peter's cousins, Princess Beatrice and Princess Eugenie, broke cover to attend the wedding.

The York sisters have largely stepped back from the public eye recently to focus on their growing families and to navigate the ongoing media scrutiny surrounding their parents - Andrew Mountbatten-Windsor and Sarah Ferguson.

Beatrice, wearing a floral printed Emilia Wickstead dress, sheltered from the rain under her umbrella with her husband, Edoardo Mapelli Mozzi. 

Princess Eugenie dressed her blossoming baby bump in a navy ensemble with matching accessories. She and her husband, Jack Brooksbank, are set to welcome their third child this summer. The couple are already parents to sons, August, five, and Ernest, three. 

The Duchess of Edinburgh looked beautiful in a pale blue Beulah London dress with a complementary basket bag. 

Peter's sister, Zara Tindall, greeted Edoardo and Beatrice with kisses as the cousins arrived at the church. 

The groom's mother, the Princess Royal, chose a yellow coat and a floral dress for her son's wedding, with a sentimental hat first worn for her daughter Zara's christening in 1981. 

The King's cousin, Lady Sarah Chatto, was pictured among the guests. 

Lady Sarah Chatto's brother, David Armstrong-Jones, 2nd Earl of Snowdon, also put in an appearance alongside his girlfriend, Isabelle de La Bruyère.
