Prince Philip looked relaxed as he rode his horse and carriage at Windsor Castle today – a day after attending the Polo with the Queen.
Wearing a flat-cap, the Duke of Edinburgh, 97, was seen taking in some fresh air in the castle grounds, while accompanied by his aides.
He looked to be in good spirits and was seen chatting away as he took hold of the reigns this morning.
Philip, who was dressed in a green jacket and beige chinos, is known for his love of carriage-driving, returning to the hobby just two months after having a hip operation.
His appearance comes a day after he joined the Queen at the Guard’s Polo Club in Windsor Great Park.

Philip, who retired from public duties last year, looked to be in remarkably good health as he attended the star-studded event on Sunday.
He recently recovered from a hip operation in April, but still managed to attend Prince Harry and Meghan’s wedding at Windsor Castle last April.
It appears that Philip has been keen to return to his beloved hobby of carriage driving while staying at Windsor Castle.
In fact, he was seen steering his two-horse carriage around the grounds of the castle just last week.

Carriage-driving has been a favourite past-time of the Duke since he gave up playing polo during the 1970s.
He raced carriages near Norfolk before going on to represent Britain at several world and European championships.
Last month, he revealed that one of his carriages, dubbed the Balmoral dog cart, ‘had to be rebuilt every year because it got smashed up regularly’.
Since retiring from his official duties, Philip has been seen in public less frequently, missing Trooping the Colour ceremony just over a week ago.

The Queen was seen riding in her carriage alone during the traditional parade, while the Duke of York took over from his father as Colonel of the Grenadier Guards.
Philip celebrated his 97th birthday privately with family last Sunday, but the occasion was marked more formally with a 41-gun salute in Hyde Park last week.
Kensington Palace also paid tribute to Philip on his birthday, posting on Twitter ‘Wishing the Duke of Edinburgh a happy 97th birthday!’ alongside two pictures.
A Buckingham Palace spokesperson confirmed that Philip would be spending the day privately on his first birthday since retiring after a lifetime of public service.

The nonagenarian conducted his final solo public engagement in August, the last of 22,219 attended since the Queen ascended to the throne in 1952.
Since then, he has spent much of his time at Windsor, and at the Queen’s private Sandringham estate in Norfolk, with occasional visits to London.
Although the Duke has stepped down from public duties, his roles within the royal family continue.
While the Queen focuses on affairs of state, Philip is in charge of matters such as running the royal estates, and maintains a small office dealing with correspondence.
