The Duke of York was photographed behind the wheel of a Range Rover on May 23. The photo showed the Queen’s second son smiling broadly as he drove into Windsor.
Prince Andrew appeared cheerful while driving and was spotted wearing a blue buttoned up shirt.
His appearance comes hours after it was claimed the Duke will attend Garter Day on June 13 – one of the most prominent royal events of the year.
Andrew’s presence would also reportedly be noted in the Court Circular, with the Registry taking note of any official events attended by working royals.
A source in the palace told the Telegraph that the inclusion of Prince Andrew in the royal diary would be “standard practice”.
The registry normally only records official events performed by working members of the Firm.
However, non-senior royals may also appear on the calendar if they attend important gatherings, such as Trooping the Color and thanksgiving services.
Prince Andrew was due to attend Garter Day in a personal capacity this year as one of the Royal Knights of the Order.
This title is considered a private one as it is conferred directly by the Queen as the Sovereign of the Order, who appoints her knights without consulting the ministers.

The Duke relinquished public duties in November 2019, following his interview with Newsnight’s Emily Maitlis.
In January, Buckingham Palace announced that he would no longer perform royal duties and that he had returned his military and royal patronage to the Queen.
Andrew last attended a public event in March when he accompanied Her Majesty to Prince Philip’s thanksgiving service.
Mother and son arrived at Westminster Abbey together and Andrew walked with his mother from a side entrance at Poets’ Corner to the front rows of seats.
Traditionally, hundreds of people queue up to watch the Garter Knights join in a procession through the grounds of Windsor Castle in their traditional velvet robes and plumed hats.
Garter Day normally includes a ceremony in the throne room of the Garter, lunch in the Waterloo Chamber, followed by a procession to St. George’s Chapel and a service.
It is not yet known whether the Queen will attend this event next month, as her attendance is dependent on her health.
The monarch suffers from episodic mobility issues, which has forced her to reduce the number of assignments outside her hometowns.
This year’s ceremony will be particularly poignant, as it will be the first since the start of the pandemic.
In addition, it will be the first to be attended by Camilla, Duchess of Cornwall, whose admission to the Order was announced on New Year’s Eve.
This was widely seen as a sign of the Queen’s approval of the work of Prince Charles’ wife and in recognition of her growing role within the firm.
Camilla is the first royal to join the Order since 2008, when Prince William was made a knight.
Other royals have been inducted into the Order over the years, including the Princess Royal, Prince Charles, and Prince Edward.
The Order of the Garter is the highest knighthood in the British honors system.
It was founded by Edward III of England in 1348.
Appointments are normally made in recognition of a national contribution, for public service, or for personal service to the sovereign.
