Prince Andrew and Sarah Ferguson drive to Windsor Castle to walk their corgis ahead of Duchess’ appearance on This Morning

Prince Andrew accompanied his ex-wife Sarah Ferguson as the couple drove to Windsor Castle on Sunday.

The ex-couple, who still live together at the Royal Lodge in Windsor Great Park, drove a Landrover Defender along the Long Walk to the castle grounds and walked their corgis.

Sarah, 64, took in the late Queen’s corgis after her death last September, and are regularly seen walking in and around Windsor.

The appearance comes as Sarah Ferguson – better known as Fergie – is due to guest edit This Morning today.

The Duchess will offer relationship advice during her own aunt segment.

Fergie will join Alison Hammond and Dermot O’Leary for the special show, which she will also edit with boss Martin Frizell.

She said: ‘I’ve appeared on This Morning before but this time I’m returning with a very different role.

‘I love live TV and am a huge fan of the show, and the whole team are always great to be around.’

She added: ‘I’m thrilled to be guest editing the show, which means I get to explore some of the topics I’m passionate about.’

Some of the other topics she will discuss include the importance of defibrillators, how best to rehome a dog, how to protect your skin, as well as an interview with Sir Cliff Richard.

This Morning’s editor Martin Frizell said of his new guest signing: ‘We’re all delighted that Sarah, Duchess of York, wanted to come back here and I’m very pleased that she will be making some of my decisions on Monday.

“She has a great understanding of the show and how television works, and I think viewers will be really interested in the running order she puts together.”

There is no suggestion yet that Fergie – Prince Andrew’s ex-wife – will be a permanent presenter, but This Morning bosses have been testing several stars as they search for a new duo following the departure of Holly and Phillip last month Schofield in May.

The late Queen, who owned several of the breed throughout her life, was survived by corgis Sandy and Muick.

Speaking at the Henley Literary Festival, Sarah said she is acutely aware that the two new additions to her household are ‘national treasures’ who are ‘well educated’.

Because Sarah and Andrew already shared five Norfolk terriers, the two corgis had to integrate with them.

She said, “They’re all balanced, the carpet moves when I move, but I’m used to it now.”

The dogs were a gift to the Queen from Andrew and his daughters Princess Beatrice and Eugenie after the death of the Duke of Edinburgh.

It was believed that Andrew and Sarah had walked the dogs in the months leading up to the Queen’s death.

The queen owned more than thirty sandy, short-legged dogs during her reign after her father gave her her first corgi for her 18th birthday.

Her dogs were given the royal treatment, they had their own rooms with raised wicker baskets and meals of beef, chicken, rabbit, liver, cabbage and rice prepared by a chef every evening.

The appearance comes amid rumors that King Charles privately believes his younger brother ‘has no long-term future’ in his royal household, despite giving Andrew more time to prove he can afford his upkeep of the country house.

A family friend said: ‘To be honest, I didn’t expect the Duke of York to live at Royal Lodge in the long term. If he could afford the upkeep, he would like to stay. But the chances of that happening are honestly slim.

“He and the Duchess… are rattling around in a huge property that they simply can’t afford.”

The king cut Andrew’s annual allowance – believed to be around £250,000 – following the emergence of the Jeffrey Epstein scandal. Andrew is said to have paid Epstein sex abuse victim Virginia Roberts £12 million to settle a case she brought against him out of court – allegations he strongly denied.

Last month, Andrew was pictured riding through Windsor Great Park on horseback.

The father-of-two wore navy blue riding breeches and a zip-up sweater with a royal code on it for the outing, making sure to don a riding helmet and gloves.

In September he seemed to be enjoying his equestrian activities and driving a Range Rover very regularly.

The pictures follow reports that the beleaguered Duke of York has been given permission by the monarch to stay at his Windsor mansion ‘indefinitely’ after they ‘agreed a new deal’.

The pair are at loggerheads over Charles’s demand that Andrew and his ex-wife Sarah move the 30-room royal property – which has problems with damp and needs several million pounds worth of repairs – to a smaller area, such as if it Harry and Meghan’s old home, Frogmore Cottage.

The Mirror reported last month that Andrew had been granted a stay of execution after Charles accepted that his brother would be given time to prove he can afford the upkeep of the mansion.

Several well-placed sources in royal circles have told the Mail that the prince is not being “realistic” about his financial situation after being forced to step back from his public duties.

A family friend said: ‘It’s all a bit cloud cuckoo land I’m afraid. No one, not least His Majesty, believes there is any realistic chance that the Duke of York can keep the roof of the Royal Lodge over his head in the long term.

‘It is a gigantic building and an estate that requires a huge amount of maintenance.’

The King’s powers to remove Andrew are limited because he took over the late Queen Mother’s Grade II listed building from the Crown Estate on a long-term lease in 2004 and funded many millions of pounds worth of renovations. If King Charles were to persuade him to move, the Crown Estate could even owe Andrew money.
