Senior royals including Charles, William and Kate gather in Windsor for baby Archie’s christening

Senior royals are gathering in Windsor for baby Archie’s christening, but mystery still swirls over who the royal couple have chosen as his godparents.

Prince William, Kate and Prince Charles are expected to attend the christening although the Queen will not be present due to a diary clash.

Baby Archie will wear the historic royal robe, donned by his cousins Prince George, Princess Charlotte and Prince Louis, for the ‘small, private’ ceremony in Windsor castle today.

He will then have his portrait taken in the same drawing room as his parents’ wedding photos and where Charles and Diana celebrated Harry’s own christening.

Harry and Meghan have refused to reveal who the godparents will be, despite billing the public for more than £2.4million for the renovation of Frogmore cottage.

Archie will be the ninth royal to be christened in the Honiton lace and white satin gown (pictured: Prince George wearing the gown at his christening in October 2013)

James, Viscount Severn was the first to be christened in the gown in April 2008

It was also used for Savannah (pictured in 2011 with her parents and the Queen) and Isla Phillips

Baby Archie will be dressed in the Honiton lace and white satin gown, first used in 2008 for the christening of James, Viscount Severn, as he is recognised as the ninth royal baby in line to the throne. 

The frilly cream outfit is a replica of the intricate gown made for Queen Victoria’s eldest daughter, and used for all royal baptisms, until Lady Louise Windsor’s in 2004.

It was created by the Queen’s dresser Angela Kelly, and features the same lengthy skirt and elaborate collars and bow as its predecessor.

The original robe, made in 1841, was worn by the Prince of Wales, the Duke of Cambridge and Prince Harry among others, and has now been carefully preserved. 

Archie's official portraits will be taken in Windsor Castle's Green Drawing Room, where Harry and Meghan's wedding pictures were taken in May 2018

In keeping with tradition, the water used for Archie’s christening will be holy water from the River Jordan, where it is said Jesus was baptised by John the Baptist. 

The ornate silver gilt Lily Font – part of the Crown Jewels – will also form part of the proceedings. 

The baptismal font, commissioned by Queen Victoria and Prince Albert in 1840 after the birth of their first child, Victoria,  was first used at The Princess Royal’s christening in 1841 and has been a feature of Royal christenings ever since. 

The official photographs of Archie’s christening will be taken in the Green Drawing Room at Windsor Castle, a historic backdrop.  

The royal family also celebrated Harry’s christening in the same room back in 1984.

Adorable footage shows a very young Harry gurgling and smiling at the camera as he wears his great-grandmother’s christening gown, while his mother Princess Diana proudly holds him on a chair identical to the one he posed on alongside Meghan last year.  

In the historic video, broadcast as part of the Queen’s 1984 Christmas message, the grand reception room is filled with familiar faces of the royal family who are celebrating baby Harry’s christening. 

A cheeky Prince William steals the show, running circles around family members before being scooped up by his father Prince Charles.

As well as family engagements, the Green Drawing Room has been a popular stage for the Queen to host official engagements – hosting the Indian prime minister in 2009 and the first Irish head of state in 2014. 

But this came after a lengthy process of renovations after the room was gutted by a devastating fire in 1992.   

Royal babies must be christened owing to the Queen’s role as Defender of the Faith and Supreme Governor of the Church of England.

They are often welcomed into the Christian faith within weeks of being born – in Archie’s case, the ceremony comes exactly two months after his arrival on May 6.

Prince George was a little older and was three months old when he was christened, while Louis and Charlotte were both also around two months. 

Prince William was baptised on August 4 1982 at the age of six weeks, while Harry was three months old. 

The Prince of Wales was one month and one day old at his own christening. The Queen was just five weeks old when she was christened.     

At Archie’s ceremony today members of the St George’s Chapel Choir will sing before members of the Royal Family including The Prince of Wales and The Duchess of Cornwall and The Duke and Duchess of Cambridge.

The Queen is, however, unable to attend her new great-grandson’s christening after a major diary clash. 

‘Her Majesty was already scheduled to be in Scotland for her annual Holyrood Week and had a prior engagement at the weekend,’  a senior employee at Buckingham Palace told the Daily Mail. 

Meanwhile the Duke and Duchess of Sussex have reportedly shunned celebrities as godparents and instead turned to a group of friends whose children played a key role in their wedding.  

Royal sources said last night that Meghan and Harry picked ‘close and old friends’ for the roles amid a backlash over the royal couple’s refusal to identify them because they are ‘private citizens’.

The chosen few are likely to include Meghan’s friend Benita Litt and Harry’s childhood mentor Mark Dyer, while more-notable names including Jessica Mulroney and Serena Williams are out.

Ms Litt is an old friend from Los Angeles whose daughters Remi and Rylan – both Meghan’s goddaughters – were bridesmaids at the couple’s wedding.
