Princess Eugenie goes incognito as she joins husband for a coffee run in first sighting since her father’s arrest… amid growing mystery over mother Fergie’s whereabouts

Princess Eugenie was photographed with her husband Jack Brooksbank today for the first time since the arrest of her father Andrew Mountbatten-Windsor.

The 12th in line to the throne wore a casual outfit with Nike trainers, blue tights, a jacket and a North Face baseball cap as he grabbed his coffee in West London.

Eugenie was seen standing next to her husband, who was wearing a colorful hat, while talking on the phone in an alley outside Hagen Espresso Bar in Notting Hill.

It follows days of police searches at Andrew’s former home at Royal Lodge in Windsor, following his arrest on suspicion of misconduct in public office last Thursday.

The former prince was detained for 11 hours on his 66th birthday while police officers searched his Sandringham property before he was released under investigation.

Andrew is accused of sharing sensitive information with pedophile Jeffrey Epstein during his time as Britain’s special representative for international trade and investment.

Following Andrew’s arrest, former US ambassador Peter Mandelson was also detained yesterday on suspicion of abuse of public office and was released on bail.

Eugenie’s mother, Sarah Ferguson, has spent time in the French Alps, the United Arab Emirates and a private clinic in Zurich in recent months, but her current whereabouts are unknown.

Eugenie was holidaying with her family in the exclusive Swiss ski resort of Gstaad when her father was arrested last week and was reportedly ‘in a state of distress’.

His parents, Andrew and Fergie, feature prominently among the three million pages of Epstein files released by the US Department of Justice last month.

Fergie’s emails to the pedophile financier revealed she took Eugenie and Beatrice to visit Epstein days after he was released from prison on child prostitution charges.

Other messages from Fergie to Epstein even mentioned Eugenie’s sex life; One described the princess as being away for a “silly weekend” when she was 19.

Eugenie was spotted in Switzerland last week with Mr Brooksbank and his sons August and Ernest as they dined at the exclusive Restaurant Waldmatte in Gstaad.

One person who spotted him at lunch told Hello!: ‘I was surprised to see him because I thought he would keep a low profile in light of everything that was going on.’

The family were with friends who joined them at the restaurant, which has a large terrace and impressive views of the Alps, although they chose to stay inside.

The diner added: ‘Eugenie and Jack were with the children, the nanny and a group of friends. They were tucked into a corner and casually dressed in ski clothes and jackets, and Jack was wearing a beanie hat as they both browsed the menu.’

Earlier this month, Eugenie left the UK for Qatar, where she made her first public appearance since the new Epstein files were published.

He was a director of the art dealer Hauser & Wirth and worked at a high-end contemporary art fair in Doha.

Eugenie and Beatrice were previously said to be ‘horrified’ by the embarrassing tranche of emails their mother sent to Epstein.

Sources close to the sisters also said they were ‘horrified’ and ’embarrassed’ by photos of their father kneeling over a mystery woman lying on the floor of Epstein’s New York mansion.

Although he was stripped of his title last year, the former Duke of York is still eighth in line to the throne and an Act of Parliament will need to be passed to depose Andrew and prevent him from becoming king.

The UK Government is expected to consider introducing such legislation after police complete their investigation into the King’s disgraced brother.

Separately, emails in the Epstein files show that Fergie introduced her goddaughter to Epstein after she first served time in prison for soliciting prostitution from a child.

She gave her former bridesmaid’s daughter Poppy Cotterell’s contact details for the late sex offender and added: ‘With you! Lots of love.’

Fergie sent Epstein her goddaughter’s details on November 12, 2010, 16 months after she was released from prison in Florida.

The emails reveal that Epstein set up a meeting with the then-22-year-old, considering hiring him and donating $100,000 in his name to a children’s health charity.

Miss Cotterell’s mother, Carolyn, was the former duchess’s maid of honor and godmother to her eldest daughter, Beatrice.

On Saturday, the Mail revealed Fergie had checked into the world’s most expensive wellness clinic and was left devastated by details of her close friendship with Epstein.

Although Andrew has been photographed numerous times in Windsor and later at his Sandringham estate, Fergie has not been seen in public since last year.

​This has led to global speculation about where the former royal family lives; Before the Mail newspaper found that he was housed in a famous Swiss clinic most of the time.

A month ago, Fergie secretly sought refuge at the world-famous £13,000 Paracelsus Recovery Clinic in Zurich.

Following an extended stay in the clinic, thought to have lasted several weeks, the globe-trotting former royal is believed to have spent time in both the French Alps and the United Arab Emirates.
