The Lily Font, the silver baptismal font commissioned by Queen Victoria and Prince Albert in 1840 and used in royal christenings ever since, will be used, just as it was for Archie’s cousins Prince George, Princess Charlotte and Prince Louis. Like them, Archie will wear the replica of christening gown originally made for the Princess Royal’s baptism in 1841 and worn by royal infants from the then-Princess Elizabeth, her children and all but her youngest grandchild. In 2008, a new version of the fine Honiton lace gown was handmade by dressmaker to the Queen, Angela Kelly, after the original was deemed too fragile to be used by a new generation. The company’s van, along with other suppliers, was seen entering Windsor Castle early on Friday morning. Buckingham Palace has confirmed details about select formal elements of the christening, which they have previously described as a “small private ceremony”. While the Duke and Duchess will no doubt incorporate their own style of hosting for a tea party with friends afterwards, the ceremony itself will be imbued with many of the same traditions seen in Royal christenings for decades. The Archbishop of Canterbury, who will leave this weekend’s General Synod to travel to Windsor, will take the service, using water from the River Jordan for the baptism. A newborn Archie Mountbatten-WindsorCredit:PA His life to date has diverged somewhat from royal convention, with his parents insisting he is a private citizen and should be treated as such.But in at least one respect, Archie Mountbatten-Windsor will be welcomed in a traditional royal manner, with a christening gown used for generations, water from the River Jordan and the choir of St George’s Chapel. Archie, who is two months old, will be christened today at the Queen’s private chapel in Windsor Castle, with official photographs taking in the Green Drawing Room also used for the wedding pictures of his parents, the Duke and Duchess of Sussex. The guestlist, limited to around 25 people, will include just four members of the Royal Family: the Prince of Wales and Duchess of Cornwall, and Duke and Duchess of Cambridge. It is understood that no members of the Royal Family will be among the list of godparents, with the Queen and Duke of Edinburgh missing the ceremony due to long-standing commitments in Sandringham.

Willow Crossley, the Cotswold florist known for her natural, rustic arrangements, is understood to be providing the flower arrangements, after impressing the couple with decorations for their Royal wedding evening event at Frogmore in May 2018.

Names of godparents – described as all “genuine friends” rather than celebrities or public figures – will also remain a secret in line of the wishes of the couple and their friends, a source said. Lindsay Roth and Genevieve Hillis, the university friends of the Duchess who visited Wimbledon with her on Thursday, are understood to be part of the celebration, while Serena Williams has ruled herself out, and Canadian stylist Jessica Mulroney posted a mystery social media message about travelling away from her family this weekend.Asked whether the names of godparents will eventually become part of the public record, in the same way as Archie’s birth certificate did in May, a spokesman for the Church of England said all baptisms must be registered and would normally be made public.“However the register to be used in this case is held privately by the royal household on behalf of the Crown and we understand that it has never complied with the usual requirement,” he said. Members of the choir of St George’s Chapel, where the Duke and Duchess of Sussex got married and Prince Harry was christened, will sing at the ceremony. Official photographs will taken by Chris Allerton, who also captured the Sussex’s evening wedding reception, in the Green Drawing Room. The register will eventually become part of the Royal Archive, where it may be accessed by the historians of the future in decades to come. On Friday night, the first royal super-fan, 64-year-old John Loughrey, arrived in Windsor to celebrate the christening.Sign up for our brilliant free newsletter, Your Royal Appointment, and get royal news and analysis sent straight to your inbox every Wednesday.
