Another headache for the Norwegian royals: Future queen Ingrid Alexandra looks up to her 'black sheep' older brother as a 'role model' – so how will the family navigate stormy waters amid his assault charges?

Princess Ingrid Alexandra has more than once spoken about her close bond with her older brother Marius Borg Høiby – who she has cited as a 'role model'.

So as the future Queen of Norway, 20, prepares for a life in the spotlight one day, it's likely the last few months have been difficult for her, after her beloved role model, 27, was arrested in August for assault and now faces multiple cartoons.

Crown Princess Mette-Maritt's son from a previous relationship, often referred to as the 'black sheep' of the Norwegian royal family, was first arrested at the beginning of August, after a woman was left in hospital with her injuries following an attack.

The following month he was arrested once again, for apparently violating an imposed restraining order. He was said to have been released the following day.

As the Norwegian royal family keeps quiet about the charges against Marius as they weather the charges against him, they may also have to grapple with how the future Queen looks up to her troubled brother.

Ingrid – who started her military training in January and is set to serve a year at the Engineer Battalion in Brigade Nord before going to Skjold camp in Indre Troms – has always been close with both her brothers.

Speaking at her 18th birthday in 2022, the young royal got emotional as she thanked Marius and Magnus, who is two years younger than her.

'Marius, thank you for everything I have learned from you, and for us to talk together about everything,' she said, as reported by Hello!.

'Thank you for always protecting me. Magnus, you are always kind to me when I need it. Thank you for giving me a hug when I have a little extra tough day.

'I'm so proud to have you as brothers.'

That same year, speaking to local broadcaster NRK, she listed Marius and Magnus among her 'role models'.

As per a translation by Royal Watcher, Ingrid said she has 'always looked up' to her older brother.

'Magnus, my little brother – I have seen him go from small and shy to big and adult. He has proper control over his affairs now,' she revealed.

'And then there is Marius, who I may have always looked up to. Not necessarily because he's so cool or things like that, but maybe more because of the loyalty he shows to other people.'

It's likely to be a turbulent time for the future queen of Norway, 20, as her troubled elder sibling, 27, was arrested in August for assault, and again in September. Marius and Ingrid pictured as children, with Crown Princess Mette-Marit and Crown Prince Haakon in 2004

And it's clear that both brothers appear to care deeply for the Princess too.

Speaking at her 18th birthday, her father Crown Prince Haakon said: 'You have all of us who love you.

'Marius and Magnus – who will always be there for you, just as you will always be there for them. Mamma – who you can go to whenever things are difficult, who is such a good listener, and who can always help pinpoint the problems and find solutions.

'And of course you have me – and your entire extended family.'

And her mother Mette-Maritt added: 'As Pappa said, the two of us are now standing here with you together with Marius and Magnus, your grandparents on both sides and your extended family. Everyone who loves you the most.'

Earlier this month, the stepson of Crown Prince Haakon, often referred to as the 'black sheep' of the royal family of Norway, was taken into custody after breaching a restraining order.

The restraining order in question was for the protection of Rebecca Helberg Arntsen, whom Borg Høiby admitted to assaulting, in a booze and drug-fuelled attack on 4 August, which saw him arrested for the first time and held in a police cell overnight.

The order was not made immediately after the attack, but after Borg Høiby reportedly contacted the victim on several occasions following the assault.

According to Norwegian tabloid Se Og Hor, Borg Høiby, 27, allegedly contacted his victim, whom he has previously referred to as his 'girlfriend', on Saturday, September 7, from a hidden telephone number.

In a statement via his lawyer, Borg Høiby has strenuously denied the claim. Defender Øyvind Bratlien slammed the arrest as being made on 'thin' evidence and accusing the police of 'reverse discrimination'.

As reported by The Telegraph, on September 13 Marius was arrested – and was said to have been released the following day.

Meanwhile the charges against Borg Høiby have expanded to also include three more victims, after other women came forward in the wake of his arrest.

One of the further victims has not been named. However, two have been named as Borg Høiby's exes Juliane Snekkestad and Nora Haukland.

The Norwegian royal family was rocked by Borg Høiby's first arrest at the beginning of August, after Rebecca Helberg Arntsen was left in hospital with her injuries following the attack.

A week after his arrest, Borg Høiby sensationally admitted to the assault on Rebecca, whom he referred to as his 'girlfriend' (her lawyers have refuted this claim).

When he turned 20, the royal court announced Marius was stepping away from public life and his profile was removed from the family's official website

In a statement issued via his own lawyer, Borg Høiby said he suffers from 'several mental disorders' and has 'struggled with substance abuse for a long time', which he said is summing up treatment for.

The statement read: 'Last weekend something happened that should never have happened. I committed bodily harm and destroyed objects in an apartment in the intoxication of alcohol and cocaine after an argument.

'I have several mental disorders which mean that throughout my upbringing and adult life, I have had, and still have, challenges. I have struggled with substance abuse for a long time, something I have been in treatment for in the past.

'The drug use and my diagnoses do not excuse what happened in the apartment at Frogner on the night of Sunday last weekend. I want to be responsible for what I have done, and will explain myself truthfully to the police.

'For me, the most important thing is to say sorry to my girlfriend. She deserved neither what happened that night, nor the extreme pressure from both the Norwegian and foreign press afterwards.'

Mette-Marit's oldest son also apologized to his family for his actions that have 'greatly affected you'.

Borg Høiby, son of Crown Princess Mette-Marit from a previous relationship, was raised by his mother and stepfather with his half-siblings, Princess Ingrid Alexandra, 20, and Prince Sverre Magnus, 18, but unlike them he has no official public role .

The arrest and his admission cast a shadow over the recent royal wedding in Norway as Princess Martha Louise wed American Shaman Durek Verrett on August 31 in Geiranger Fjord.

Ahead of the nuptials, the Norwegian palace confirmed Borg Høiby would not be attending the wedding with his mother, stepfather and half-siblings. Norwegian media later reported that the former engine mechanic had turned down the invitation to attend an Italian wedding of the son of a billionaire and an influencer.

However, when news of the assault and arrest came to light, Borg Høiby was uninvited from that wedding after guests threatened to pull out if he was in attendance.

Marius arrived in Pisa ahead of the wedding of Karianne Vilde Spetalen and Kristian Spetalen, both 30.

It is believed that guests thought Norwegian press would travel to Italy to document the wedding if Marius was present, a circumstance some did not feel comfortable with.

Sources told Se og Hør that Norwegian influencer Karianne also faced backlash from her family regarding Marius's planned attendance.

The scandal of the Norwegian royal family's 'black sheep' Borg Høiby's arrest has damaged some Norwegians' affection for their monarchy, MailOnline previously revealed.

Traditionally the people of Norway are even more fervent royalists than Brits, but we found that young people in particular were less forgiving of Borg Høiby's behavior.
