The Queen Consort joined senior members of the royal family on Wednesday for the lying-in-state procession for Queen Elizabeth II - where her coffin was carried to Westminster Hall to lie in state for the nation to pay their respects. Grieving Camilla sat beside the new Duchess of Cornwall as they travelled by car behind Her Majesty's coffin, while their husbands - King Charles III and Prince William - marched in homage behind the coffin on foot.
But Camilla, who appeared sombre dressed in black with a black hat, was initially joined by her right-hand woman Sophie Densham to travel through the streets of London to Buckingham Palace, where they passed thousands of mourners lining the streets. Sophie is her private secretary and has been at her service for more than a decade.
And it is likely she will continue to play a vital role in support for the new Queen Consort and King. Ms Densham commenced her career as a secretary for the Memorial Gates Trust - a charity that was set up to build a memorial to those from India, Africa and the Caribbean who served in the First and Second World Wars.

She then joined the royal household staff, moving into the then Duchess of Cornwall's private office in 2008, according to the Daily Mail.
Last year, Ms Densham was then made Camilla's private secretary.
She was at the service of Camilla earlier this week for the proclamation ceremony, which saw her boss attain her new royal title.
The Queen Consort was by her mother-in-law's side at the Balmoral estate during the Queen's final hours last Thursday.
She and King Charles were already close by running errands when royal doctors announced they were concerned over Her Majesty's health, where it was later announced by the Palace that she had died peacefully.
On Wednesday, the Queen's coffin left Buckingham Palace for the final time and travelled to Westminster Hall, where a 20-minute service was led by the Archbishop of Canterbury accompanied by the Dean of Westminster.
During the service, the royals stood in formation facing the coffin on its purple-covered catafalque, which was flanked by a tall, yellow flickering candle at each corner of the wide scarlet platform.
The King and Queen Consort stood together a metre or so apart, with Princess Anne and Vice Admiral Sir Tim Laurence behind them, then Prince Andrew alone, and in the next row Prince Edward and Sophie Wessex.
Behind them were the Prince and Princess of Wales, William and Kate, with Harry directly behind William and Meghan behind Kate.
King Charles, dressed in ceremonial uniform with the rank of Field Marshal, shed a tear after his mother made her final journey.
His Majesty carried his Field Marshal Baton presented to him by the Queen when he became Field Marshal in 2012 and was also wearing the Order of Merit, the decoration on his neck, with the Order of the Garter Sash and Star.
Following the service, the first members of the public have been able to file into Parliament's Westminster Hall to see the Queen's coffin, after waiting for hours in line to pay their respects.
The Queen will lie in state until 6.30am on Monday, September 19 - the day of her funeral.
